We set up the first lightstand with an umbrella, and the wind almost blew my gear and girl away. Debra asked, “Bare flash?”. I replied, “Yes, I think that would be best.” So we set up 3 light stands, each with a bare BB560 flash and Blackbelt receiver. We moved the lights around as needed, sometimes lighting Brian in the car with 1 or 2 lights (plus the sun of course). In a few images we had 1 or 2 lights on Brian, while at the same time having 1 or 2 lights on the car, just to open up the details that would otherwise be black shadows from the low sun.

I shot these images on a Canon 5dmk2, mostly with a 70-200 lens, and a few wide angle shots were done with a 17-40 lens. Lighting conditions being constant, the shots were taken at ISO 50 or 100, from f5.6 to f8, at a 1/200 shutter speed (the maximum sync speed for the BB560). Flash output was set to 1/2 power and sometimes bumped up to full power as needed. I have been using the BB560′s for sometime now and this was one of those shoots where the reliability and power output was really put to the test. They worked flawlessly.

Photos were edited in Adobe Lightroom 4, the black and white images were done with Nik Silver Eex Pro 2, and Nik Color Efex Pro 3 Tonal Contrast preset was used on some of the color images.

Why Was This Difficult

Generally this may not have been too hard of a shoot but if we look at the first test image here we can see that the label is very transparent and that is wraps around the bottle leaving about a 1” gap in the back. The gap lets in more light than the rest of the label causing the front of the label to wash out. We can also see the lettering on the back of the bottle which is very distracting to the overall image.

Lighting this wasn’t overly complicated, there were three Blackbelt Lighting BB560 speedlites on either side at about a 45 degree angle with no modifiers. The background was lit with a third BB560 that was flagged to cut down on some of the light from the flash hitting the bottle directly.

The lighting worked, the background went solid white, the colors were accurate, but that label was just going to work.

I Don’t Suck At Photoshop

I made a number of different attempts including cutting the label down and putting it on a new bottle but the label just wasn’t popping the way we wanted it to. It was time to take some more drastic moves in order to make this shot work.

First off we shot a clear bottle of water. Getting this shot would give us a properly lit bottle with enough reference lighting on it to enable us to composite in the label.

Next we used a flatbed scanner to scan the label in. This gave us a nice vibrant label to work with and we can always adjust the transparency of it in Photoshop.

With the label composited in, using a small amount of Warp to get it all lined up on the bottle, we now have an image that looks very flat and pretty well obviously composited. In order to fix this, we need to bring back the lighting from the clear bottle shot and maybe adjust the opacity of the label layer slightly.

Now we are getting somewhere. The extended lines of the lighting help to give it back a rounded look and since they match the clear bottle light lines, we know it should look pretty natural.

The Finishing Touches

Finally, the client wanted a shadow underneath the bottle to make it look like it was floating. To accomplish this I copied the bottom of the bottle, flipped it vertically, and then applied a Gaussian Blur to it.

Summary

This should go to show you that a good photographer needs more skills than just being to setup lighting and press the shutter. A good knowledge of Photoshop is essential in order to get the desired result. While I am not saying that you can always just “fix it in Photoshop”, its just that there are times when there really are no options and you need to pull out the stops and do whatever it takes in order to make the shot come out as you intended.

Isn’t “Suck” a little harsh?

Actually, to say that the audio recording sucks is an understatement. My two-year old $600 Vixia palm sized camcorder does better audio than my 7D. So no, the poor audio recording is a major failure on the camera manufacturers part and can actually be fixed via firmware if they chose to. One thing that may surprise many people is that they get better sound from the on-board microphone than they get with a high-end studio microphone. No way, the cheap, tiny, built-in mic works better…how is that possible? The answer is the one thing that makes the on-board mic work “so so” and higher end microphones almost unusable is Automatic Gain Control (AGC). What AGC does is to monitor the audio stream and then boosts the audio signal to make sure it is picking up the audio. The reason this sort-of works on the built-in microphone is because of the ambient noise in most situations. With any ambient noise, the AGC will “hear” some noise and the AGC won’t kick in. With a really good microphone, you can get such a clean audio signal that there is no ambient sound which will send the AGC into overdrive, thus filling the audio stream with tons of noise as it tries to boost the signal.

All the camera manufacturers have to do is to allow the ability to disable AGC in the firmware or preferably have a setting option such as High, Medium, Low, Off. This would allow for selectable gain control depending on the situation and the microphone used. That’s it, a simple firmware change and there would be no need for this post. However…none of the DSLR manufacturers have seen fit to include this obvious setting.

Creating Non-Sucky Audio

There are several ways to get really clean audio and we will look at some of these options so you can decide if one of them is more suited for how you want to work.

Secondary Recording Device

From the dawn of time (or at least since video recording started) high-end video production has consisted of using separate devices for video and audio recording. Have you ever seen a clap board and wondered what it was for? A clap board is used by the editor to sync the audio and video since they are recorded on different devices. For cinema production, this is a tried and true process so moving to DSLRs does not affect their workflow at all. For budget filmmakers who have used camcorders, moving to separate audio and video tracks can be frustrating and difficult to sync up properly. Add to this that even a slight variance between the two devices and a long film clip can actually drift out of sync. One  of the most common secondary audio devices is the Zoom H4N. I actually have the older Zoom H4 which isn’t available anymore.
Pros: Excellent Audio
Cons:  More work in post, additional expense

AGC Disabling Mixer

For post production speed it is definitely better to have the audio and video already mixed together. This prevents and audio drifting and issues with syncing (until you start using multiple cameras anyway). One solution I have found is the JuicedLink DS214 Amp which features AGC disabling. The way the AGC disabling works is that the DS214 feeds a generated tone through one of the stereo channels while sending the microphone audio through the other channel. This tone sound essentially shuts down the AGC because it becomes overwhelmed with noise thus lowering the gain to the minimum and letting the camera record very clean audio. With the DS214 costing $144, this isn’t a cheap solution but it does do the trick and as soon as the firmware allows for true disabling of the AGC control, then you can disable this feature.
Pros: Allows variety of microphone gear to work well, less work in post
Cons: Only allows for single channel audio recording, additional expense

Magic Lantern Firmware Hack

While we wait for Canon and Nikon to come to their senses, the folks over at Magic Lantern have created a firmware add-on for some Canon cameras that adds a nice set of features including audio meters and the ability to disable the AGC function. The downside here is that the Magic Lantern firmware is not available for the Canon 7D yet or for Nikon cameras.
Pros: FREE!, True AGC disabling, Auto Meters
Cons: No 7D support, No Nikon support

Summary

If you are getting started with DSLR video, it is only a matter of time before you get frustrated with trying to get good, clean audio. Hopefully you will find one of these options to suite your needs and budget to help you get exactly what you are trying to get.

Practical Uses of ND Filters

Some photographers, especially nature and landscape photographers have long been familiar with neutral density filters most notably for allowing you to shoot a scene with a longer shutter speed for scenes such as waterfalls to get that silky effect to the water.

If we go back to the basics and look at the Sunny 16 Rule, this tells us that is bright sunlight at ISO 100 and 1/100th shutter speed, we will need to be at f/16. If we adjust our shutter to our video setting of 1/50th, then we need to be shooting at f/22 for a proper exposure. While this may work in some situations, if you want any creative control over your aperture settings, you will need to cut down the lighting entering the camera, again this is a great use of ND filters. Instead of using a faster shutter, we can simply use darker ND filters to cut down the light to where we want it.

Choosing an ND Filter

Most neutral density filters are fixed at a particular setting and generally come in settings from 1/4 stop all the way to 10 stops. Buying a small selection of ND filters is certainly one option, although a much more versatile option would be a variable ND filter that lets you adjust the density across a wide range.

The Variable ND Filters from FADER are an excellent example of this type of functionality. With the FADER Filters you have a range of 2-8 stops which, if we go back to our Sunny 16 Rule, only needs four stops to allow us to shoot at f/2.8. This allows us a broad range of creative control with your aperture.

At a bit over $300, these filters don’t come cheap so if you are on a budget you might want to get a couple of less expensive ones to start off with.

Fader Variable ND Filter

Using an ND Filter

There is nothing special or magic about using an ND filter, once it is on your lens it’s just as if someone dimmed the lights and you continue to set your exposure using aperture and ISO adjustments (remember, not shutter speed because we are locking that down to 1/50th second).

The following video demonstrates this concept by shooting the same scene and adjusting the FADER filter to make the scene darker while opening the aperture to compensate.

Summary

I hope you are enjoying these articles on getting started with DSLR video. Even though shooting video with a camcorder or other dedicated video camera is so easy that even a kid can do it, shooting video with a DSLR is actually quite complicated and requires a very different skill set than shooting still and often requires specialized gear to get top-notch results. If you are doing any video work, please post in the comments and let everyone know what you are doing.

Not all of us have hundreds of dollars to spend on fancy gadgets like focus pullers but we can borrow from the concept and with a little ingenuity come up with a way to accomplish the same result.

Parts Needed

What you will need

I hope I don’t scare you off with this extensive list of components you will need to put together.  Ok, just kidding, odds are most of you will have the items you need lying around the house. All we are going to need are two rubber bands and a pen (I find a fine point Sharpie to work the best).

I managed to find two Sunday newspapers that I snagged the rubber bands from and stole a Sharpie off my wife’s desk.

Setup

All we need to do is to place one rubber band on the focus ring and the other rubber band on the part of the lens next to the focus ring that is not going to rotate.

To set my first focus point, I find it easier to use the photo mode’s autofocus or use Live View and zoom in close to make sure your focus is as sharp as possible. Now you make a line on both rubber bands that line up so now we have the first point. Next, we set out focus on the second focus point and mark the rubber band on the focus ring in line with the stationary band.

Focus Point 1

Focus Point 2

Now we are set to go into video mode and start shooting. When you are ready to change focus, you just rotate the focus ring to line up the second focus point line. If you are setting up multiple shots, you can use different colors of pens to correspond to different setups.

Results

Your finished result will be entirely dependent on how well you originally set your focus points and how smoothly you can turn the focus wheel without it being jerky or moving the camera. With a bit of practice, you should be able to get pretty good results.

The video below demonstrates what you can do with this setup. The video was shot on a Canon EOS 7D with a Sigma 24-70 f/2.8 lens and is actually my very first attempts at using the setup.

As you can see, the results aren’t too bad for a first try. If you are an aspiring filmmaker on a tight budget, give this technique a try and see if you can add some nice focus pulling effects to your videos. If you have done any, please post links in the comments.

ISO and Aperture

The good news is that two out of three aint bad. What I mean by this is that ISO and Aperture affect video exactly the same way that they affect stills. ISO will make the sensor more sensitive to light so just like stills, you can increase the light into the camera by increasing the ISO setting which, just like stills, will add digital noise to the image.

Just like still images, Aperture will open or close the lens’ aperture diaphragm to allow more or less light into the camera which will affect the depth of field.

So long as you already have a good handle on ISO and Aperture, the same principles apply to both stills and video so you already well on your way.

Shutter Speed

With stills, shutter speed is fairly simple to understand, a longer shutter will allow more light but may add motion blur while a fast shutter speed can freeze motion but cuts down on the amount of light entering the camera. The confusing part is how this affects video. Many new video DSLR owners simply think this affects only the light since the frames are already moving. The reality is that the shutter speed can have a significant impact on the video image and most of the articles on the internet are painfully difficult to understand.

The traditional standard for video is 24p (which is actually 23.976 frames per second) which is very pleasing to the eye and is pretty much the standard for camcorders and DSLR video recording (much more on this is available on Wikipedia).

To achieve a film look (which has just enough motion blur between frames to look natural without being “smeary”) you need to follow the 180 degree rule which, simply put, says that your shutter speed should be double the frame rate. This is one of those times when I want to say “don’t worry about what it means, just go with it” as the technical explanation is quite…well…technical. Tyler Ginter did a really good job explaining the technical side of this on his blog post 180 Degree Shutter – Learn It, Live It, Love It.

While I am not going to try to explain the whole 180 degree shutter concept, I will instead just jump into what it really means to you and your video.

Since we already know that when we are shooting stills with action, a slow shutter speed will have motion blur and a fast shutter speed will freeze action. When we translate this concept to video, a slow shutter speed will create a smeared look to the video. If the shutter is too fast there isn’t enough motion blur to smoothly transition from frame to frame causing a stuttering or staccato effect. If you have ever looked at something moving with a CRT monitor behind it you will know what this stuttering can look like. Sometimes, this can be used for creative effect like in the opening of Saving Private Ryan.

To see how this looks in actual video, I did this quick comparison of 24p video shot at both 1/50th (yes, I know 1/48 is double the 24fps but most cameras can’t do 1/48th shutter speed so we have to take the closest option which would be 1/50th) and 1/300th shutter speed.

What about exposure?

The issue with exposure is not when things are too dark as we can open up our aperture and increase our ISO (only to a certain point before we need additional lighting anyway) but when things are too bright, we only have a few options. If you are already at a small aperture and a low ISO and 1/50th of a second will result in an over exposure the temptation is to increase the shutter speed, but this is going to violate the 180 degree rule and cause the stuttering video.

The only way to knock the exposure down is with the use of a neutral density filter. The most versatile filter is a variable neutral density filter that allows you to dial in the amount of filtering. A good example of this is the Fader ND Mark II which is adjustable from 2 to 8 stops.

The real beauty of using a filter with this much versatility is that you can shoot at the relatively slow 1/50th of a second at wide open apertures to create a very short depth of field that just isn’t possible with regular camcorders. The ability easily create different depth of field shots  is a key reason many filmmakers are jumping onto the DSLR video bandwagon.

The Exception to the Rule

Let’s face it, every good rule deserves a good reason to break it and the 180 degree shutter rule is no different. In fact, there is one really good reason to break it and that is when you are specifically shooting for video that will be shown in slow motion. If we use the basic rule of having a shutter speed that is double the frame rate, when we slow down the video we will end up with more blurry video. If you shoot at faster shutter speeds, when you slow the video down you will get cleaner looking video.

This actually brings up a major difference between shooting stills and video. With stills, our final output will be a still frame. Sure, you may use some panning and zooming in a slidehsow which may require cropping that isn’t very tight but lets not digress too much. With video, you really need to think ahead about how the video will be played back. Will the video be sped up, played at normal speed, or slowed down as this final product needs to be considered when choosing the shooting settings.

Summary

Hopefully this has helped make some sense out of the shutter speed issue with DSLRs. If you are just going to be shooting video for yourself, you may not care much about all this but if you are trying to really make your video look its absolute best, and most certainly you can achieve incredible results with the current video enabled DSLR’s, then this is one of those topics that you really need to get a handle on.

Differences between camcorders and DSLRs

Many of you are probably own some kind of camcorder. These small, handheld video cameras are actually pretty amazing for their price with 1080p video for under $700. If these little wonders are so good, why do we even need DSLR video? For one thing, the sensors in the consumer camcorders are relatively small and the have a single lens with a fixed focal length. This doesn’t allow much in terms of creative shooting like being able to blur a background. Most don’t even let you select a focus point and they try to guess what you want. Are they REALLY 1080p video, well yes, technically speaking but they are not “broadcast quality” images. Just because something puts out video out 1920×1080 resolution does not mean the image quality is going to be that great.

On the opposite end of the spectrum are DSLR’s that can shoot video. In comparison to high-end, dedicated video cameras, DSLR’s can actually have a BETTER image because the sensor size in a DSLR is larger than in a video camera and the ability to use many different lenses allows for very creative shooting.

The big downside is that most (and this IS changing) current video-DSLRs do not have full-time autofocus. This can be a huge challenge for many people who have come to rely on autofocus for their still photography. Add to this moving subjects and trying to adjust focus on-the-fly, and you can be in for a very challenging shoot. Also take into consideration that the ergonomics of a DSLR are not really suited for shooting video so trying to hand-hold a DSLR while shooting is almost certain to add unwanted shaking or movement. One of the other things to consider is going to be accessories to help you shoot video better (more on this below) which may include a tripod with a fluid head, a good microphone, a stabilization system, viewfinder enhancements, constant lights, and software to do the editing. If you go “all in” you can easily spend more on video accessories than you did on the camera body.

Getting Started

I am going to start with assuming most people are going to be shooting video that is not destined for broadcast TV or movie theaters but in future articles we will get into fine tuning our video and camera settings for those applications. For now, we will start with the basics just to get things going.

Equipment

Depending on what you are shooting, you may or may not need all of the things mentioned here and I will try to point out when and where different pieces will be used.

Tripod and Fluid Head

While you probably own a tripod, the head on it is likely not smooth enough for video. As you tilt and pan, it is very hard to get a real smooth motion. For video, you want was is referred to as a fluid head which will really make a huge difference in controlling your camera for video. If you have a tripod with a removable head, you can just buy a head made for video and use it when needed. Good fluid heads can cost hundreds of dollars but a fairly decent one such as the Weifeng WF-717AH can be found for around $70.

Monopod

A monopod can really be a lifesaver when it comes to video since it can help you steady your camera instead of trying to hold it still for extended periods of time. Another little trick is to put the bottom of the monopod into your belt or pocket and extend the monopod so the camera is eye level, this technique can help you get really smooth pans but is going to be fairly bouncy when walking. For this purpose, you can find a cheap monopod at Walmart for about $15.

Batteries

If your camera supports an add-on battery pack, I would highly recommend you get one and some extra batteries. Running your camera for extended periods (which means the LCD is on as well) can suck the life right out of your batteries before you know it.

Microphone

As you can probably guess, the on-board microphones on DSLR’s are not going to give you superb 5.1 Dolby stereo audio. In fact, its fairly poor mono audio and with no windscreen in front of it, you can pick up a lot of noise. A fairly popular microphone is the Rode VideoMic which runs about $149. I happened to have a Zoom H4 recorder which not only has two mics for recording in stereo but also has two XLR connectors so it is extremely versatile. I just needed a $2 audio patch cable and a hot shoe adapter. Of course, if you aren’t planning on recording video and always plan on just having a music soundtrack, then you really aren’t going to need a microphone.

Lights

If you have a bag full of 580 EX II’s, they aren’t going to do you any good when shooting video, you will need a constant source of light. While certainly I am a big fan of big LED light banks like Ikan’s, they are outside my budget. With a couple of small lights like the YN160 you can get generally decent lighting for about $75.

The YN160 can be mounted on-camera or on a light stand and can use seven different types of batteries including regular AA cells.

Software

This is where things can get crazy real fast. While you may find lot of people suggestion that you can use Windows Movie Maker, the video files directly from the 7D and the 5DMkII are NOT compatible with Windows Movie Maker. There are tools to convert the files but now you are getting into a real headache. If you have any software suggestions, please post them in the comments as I would love to hear about them.

I am going to do my best to offer up some suggestions here based on different price points:

Free Software

• iMovie (Mac)
  This is USUALLY free as it is bundled with most Macintosh systems (as far as I know)
• Lightworks (Windows)
  Lightworks is an open source editor that is actually quite powerful but is somewhat lacking in documentation and tutorials

Consumer Grade

• Adobe Premiere Elements 9 ($99 for Mac/Windows)
  Probably one of the better mid-range tools available and at a reasonable price
• Sony Vegas Movie Studio HD ($95 for Windows)
  Vegas is an extremely popular editing program with a very nice feature set

Pro Grade

• Adobe Premiere Pro CS5 ($179 for Mac/Windows)
  My personal choice as I work on a high-end Alienware Windows 7 machine
• Final Cut Pro ($300 for Mac)
  FCP and Premiere usually take turns beating out each other on features. With Final Cut Pro X, I think it takes the lead.

Summary

Hopefully this wasn’t too much to start off with and I really want to hear from you and find out if you are interested in more articles about DSLR video. I will leave you with this little video I did as my first video project with a Canon EOS 7D.

In this post we are going to look at how to control exposure by manipulating the different settings on the camera such as ISO, Shutter, and Aperture.

What is exposure?
Exposure is, simply put, the amount of light that enters the camera and hits the sensor. The more light that hits the sensor the brighter the scene will be. If too much light hits the sensor, parts of the image will be “blown out”, this is considered to be over-exposed. A scene that is too dark and the details in the shadows are lost is under-exposed.

Under Exposed Image

Over Exposed Image

How to control exposure
There are three camera settings that control the exposure, these are:

• ISO speed
  • Controls the sensitivity of the sensor to light
• Aperture
  • The aperture controls the size of the diaphragm over the shutter, the smaller the aperture number the more open the diaphragm is, allowing more light to enter.
• Shutter speed
  • The slower the shutter, the more light will enter the camera

We will look at these settings in more detail to see exactly how the play together later. First, you need to start thinking of light in terms of “stops”. A stop is not an exact amount of light, it is a relative amount of light, each stop of light doubles the amount of light. For example, if we have a single lightbulb as our base light source, adding a second lightbulb (doubling the amount of light) increases the light by one stop. If want to increase the light by another stop we have to again double the amount of light to four lightbulbs. Understanding this is going to be the key to understanding how the different camera settings affect our exposure.

ISO Speed
As already mentioned, the ISO speed will control the sensitivity of the sensor. The lower the number, the less sensitive. For low light you will need a higher ISO number to make the sensor more sensitive. The downside is that the higher ISO the more digital noise (grainy look) will show up which will degrade the image quality.

Each time you double the ISO speed you increase the exposure by one stop, so ISO 400 will give you one stop of exposure more than ISO 200, and ISO 800 will give you one more stop over ISO 400 etc. Some cameras have some in-between ISO settings to provide a finer level of control.

You currently see high ISO performance as being a major selling point for new DSLR cameras as this allows them to shoot in lower light conditions with less noise.

Pro: Higher ISO allows shooting in lower light conditions
Con: Higher ISO settings result in more digital noise

High ISO Digital Noise

Aperture
Aperture is a little confusing because the larger the number the smaller the size. The largest aperture lenses are f/1.0 although most of the good prime lenses start at f/1.4 – f/1.6. Zoom lenses typically are not available that can do more than f/2.8.

So besides letting in more or less light, what does the aperture actually do? The more light that comes in at a particular shutter speed, the shallower the depth of field. If you want more depth of field you use a smaller (higher number) aperture setting.

Pro: Larger apertures allow more light in and thus allow shooting in lower light conditions
Con: Larger apertures reduce the depth of field which may not be desirable

Shallow Depth of Field

Deep Depth of Field

Shutter
The faster the shutter, the less light enters the camera, the slower the shutter the more light will enter the camera. If you are shooting in low light conditions, you may need a slower shutter speed, however, too slow of a shutter and you can introduce blur from the subject moving, accidental camera movement, or both.

Sometimes a little blur can help portray movement and action, a sharp bike rider with a blurred background will make the rider look like he/she is moving fast where a tack sharp image shows no motion at all and would make the same image look boring. While blurring on other images can ruin the image.

Pro: The right shutter speed can really make an image more dramatic. Fast shutter speeds can freeze action, slow shutter speeds can add a dramatic motion blur.
Con: Fast shutter speeds require lots of light, slow shutter speeds are harder to control

Fast Shutter Speed

Slow Shutter Speed

Summary
By understanding the three variables that control exposure along with the pros and cons of each one, you will be able to better control the different options that are available to you.

The Math
Feel free to skip right over this part, this is the boring part, it’s so boring I thought of putting a picture of an artistic nude shot next to it just to keep people awake. Ok, so here we go. Before you can calculate the depth of field you first must know the circle of confusion for your camera.

Don’t get too lost on me yet, for most of us digital SLR users this is  one of two numbers. For most of us with APS/APS-C sized sensors this number is 0.019948, for full frame sensors (the big Pro cameras) and 35mm film the number is 0.02501. This represents the sensor size. Again, don’t get all lost on me yet, just remember the number for your particular camera.

The first thing we need to calculate is the Hyperfocal distance, for this calculation you will need to know the focal length of your lens. the aperture you are using and the CoC (circle of confusion) for your camera.

The math to calculate the hyperfocal distance is as follows:

HyperFocal = (FocalLength * FocalLength) / (Aperture * CoC)

Thus, the Hyperfocal distance of a 50mm lens at f/2.8 on an APS sensor (Canon 30D in my case) is 146.85 feet.

Next we need to calculate the near point which is the closest distance that will be in focus given the distance bdetween the camera and the subject. The math here (yes, it gets SO much worse) is as follows:

NearPoint = (HyperFocal * distance) / (HyperFocal + (distance – focal))

This is somewhat  complicated because the focal length is in millimeters and those of us in the US are better with feet and inches still so if you want the end value to be in feet you have to do some more conversions. If we are using the same 50mm lens, at f/2.8 on an APS sensor at a distance of 10 feet (3048mm) then our HyperFocal distance is 146.85 feet (44,749.23mm), giving us a near focus point of 9.37 feet (2,856.66mm). Are we following along still? Did I lose anyone?

Alrighty then, let’s now calculate the far point distance, this is almost the same as before but using slightly different math, so here we go.

FarPoint = (HyperFocal * distance) / (HyperFocal – (distance – focal))

Without changing our values that we used before, we now know that are rear point is 10.72 feet (3,266.81mm). Take note that the near point is actually closer to you than the subject is, typically the focus is 1/3 in front of the subject and 2/3 behind the subject.

The final step is to calculate the total amount of focal distance. This is one I can even do without a calculator, we simply subtract the far point distance from the near point distance.

TotalDof = FarPoint – NearPoint

Giving our example so far we have a total depth of field of 1.35 feet (411.48mm).

Let’s get practical
Why on earth would you want to know this? The simple answer is you may not, nor may you ever care to know it. When shooting portraits, weddings, events, and pretty much anything else it really isn’t going to matter much. However, if you are the type that wants to set up a shot and have it be EXACTLY what you want, there is simply no other way to know what the camera is going to do. This is important in macro, food, and product photography. By knowing exactly where you focus points begin and end you can more accurately design and execute precise shots.

Ok, how about the easy way?
This is kind of like taking a digital photography class and having to spend a semester cooking your own B&W film, its good to know the theory before taking on the practical application. So how can we do this easier than having to pull a scientific calculator each time you want to set up a shot?

• f/Calc Windows and Palm App (website) If you want a simple but powerful Windows or Palm based application, f/Calc does Field of View, Angle of View, Magnification, Spot Meter, f Numbers, Depth of Field and Hyperfocal distance
• PhotoCalc for iPhone (website) – Not only does it do everything for DoF, it also incorporates a sunrise/sunset function, flash exposure calculator, and Exposure Reciprocation calculator.
• CamCalc (Market) Android App for Depth of field, field of view, focal length equivalents, flash calculations, color temp. conversion, miniatures, and sunrise, sunset.
• PhoforPho (Market) Android App with Exposure calculator, Hyperfocal calculator, DoF calculator, Timer, and Exposure compensation calculation for multiple exposures.

I know this has been a doozy of an article to read through just to get to some free or almost free (PhotoCalc is $2.99) tools to make it dead simple to do these calculation. Hopefully this will help you perfect your images help you to use depth of field to its full extent.

Often we try to use the fastest shutter speed possible to help avoid blur but when shooting a moving object you sometimes need some amount of blur or it can look like the subject of the image is sitting still. In many cases you want to have the sense of movement to help convey the story of the object.In the case of the ceiling fan we want to show a little movement of the blades since the moving blades is going to be more typical of what you would see by looking at the fan once installed. We also want to show that this is a five-bladed fan so we have to be careful not to have too much blur that we lose all the details.

Let’s take a look at a series of shots taken at different shutter speeds:

1/10th Second - Way too much blur

1/25th Second - Better but lacking detail

1/40th Second - Looking good

1/100th Second - Not enough, just looks fuzzy

1/200th Second - Almost no movement

As you can see the photos taken at the two extreme ranges show either far too much blur or not enough blur to make for a good image. The photo taken at 1/40th maintains a little more detail than the images shot at 1/25 making it a more suitable image for our use.

Summary

The whole point here is to get you to experiment more with shutter speeds to capture a sense of movement, action, or speed. By adjusting the shutter speed you can control how much or how little the blur effect will have.

To put it simply, on a bright sunny day, set your camera on f/16 and set the shutter speed to the reciprocal of the ISO speed. So if you are set to ISO 200, then set your shutter speed to 1/200^th. If you want a faster shutter speed then increase the shutter speed and set the ISO to match. For example, if you want to shoot at 1/400^th of a second, set the ISO to 400.

f/16 ISO 200 - Shutter 1/200th

f/16 ISO 400 - Shutter 1/400th

To compensate for overcast conditions, simply adjust the f-stop to a more open setting like f/11, and keep adjusting as needed. A good chart of recommended settings is in the following table:

By utilizing the sunny 16 rule you will help ensure that you get the right settings dialed in quickly and easily. It’s always nice to have some frame of reference when getting started. When all else fails and you don’t know what settings to start with, remember the sunny 16 rule and adjust as needed.

Getting Started
Most cameras, including newer point and shoot cameras will let you shoot in full manual mode. The problem with going manual is that if you don’t have your settings “just right” you can end up with an image that is too dark or too light. Without a basic understanding of the different settings, it can be difficult to get a good shot. However, with a basic understanding of the three variables even the most newbie photographer can learn to take better pictures by getting away from the automatic settings.

ISO Speed
The ISO speed is equivalent to the ISO speed we used to use on film cameras, this describes the light sensitivity of the film that is being used. The higher the ISO speed, the more light the sensor can pick up. For example, if your camera is set to ISO 800 you can take a well exposed image in a darker room than you could with ISO 100. By definition you would always want to run your camera in the highest ISO speed possible. While this may sound like a good idea, the downside is that the higher the ISO speed, the more “noise” will be introduced to the image, thus degrading the image quality. In most cases, you will get excellent results by using ISO 200-400 outdoors and 400-800 indoors. This does not take into account your camera model as some cameras do better than others at the higher ISO settings.

Shutter Speed

Medium Shutter Speed to Show Movement

The shutter speed is one of the easiest settings to understand as it simply means how fast the shutter opens and closes when you press the shutter button. The faster the shutter speed the better the camera will freeze the action of an event. This setting is represented in seconds, a fast shutter speed would be something like 1/2000^th of a second. A long shutter speed such as 1/30^th of a second or slower can result in blurry images if you don’t use a tripod. Like the other settings, the shutter speed also affects the amount of light that hits the sensor. The faster the shutter speed, the less light that comes into the camera. So while a fast shutter speed can freeze action, you need more and more light in order to prevent getting a dark picture the faster you set the shutter. When you cant get a bright enough image, you will need to slow down the shutter speed. In some cases you may want to get a motion blur such as a waterfall or freeway traffic, these shots require a very long shutter speed.

Shallow Depth of Field

Aperture
Understanding aperture is probably the most difficult setting for most people to grasp, because of this we wrote an entire article about it. The aperture is an adjustable opening in the lens that controls the amount of light that can enter the camera. The aperture setting is expressed in f stops with the largest opening having a smaller number so a wide open aperture is going to have an f-stop of around f/1.4. The aperture setting can have a big effect on the depth of field which allows one part of the image to be in focus and the rest of it being blurry which helps to highlight the subject of the photograph.

Starting Points
Without having a light meter or lots of experience how do you know what settings to start with? The way I learned was to set my ISO to what I wanted, typically 200-400 ISO outdoors and 400-800 ISO indoors, and put the camera in P mode and press the shutter half way down. Inside the viewfinder the camera will show the settings it will use to take the picture. Then you can put the camera into Manual mode and adjust the settings to match. After some practice you should be able to set some basic settings fairly close to what they need to be, then, by pressing the shutter half way down the camera will autofocus and then take a meter reading which should show in the viewfinder or on a display depending on your camera. Then you can adjust shutter speed or aperture to change the exposure to get it where you need.

Using the Histogram
If your camera will display a histogram after shooting an image, then you need to take advantage of this feature. By looking at the histogram of an image you can quickly tell if the image was properly exposed or not. With a digital SLR camera you want the histogram to be a nice curve with the curve being just to the right of center like our example one here. This is actually saying that the image is just slightly overexposed. With film, if you overexposed the image, you would lose detail so it was better to slightly underexpose. With digital, shadows will lose detail so it is better to slightly overexpose.

Practice Practice Practice
There is nothing that will beat getting out and getting behind the camera and learning how to use it well. If you plan on making photography a serious hobby or more, you will need to learn how to use manual mode for those times when the automatic or program mode settings just won’t cut it or for when you want to create an effect that you just can’t get any other way.

Get out and practice and be sure to post some comments and post some pictures to our Flickr group.

If you can master controlling the depth of field in your photographs you will be taking your photographs to a whole new level. What do we mean by controlling depth of field (DoF)? This is the effect where the subject is in sharp focus but the rest of the image is slightly out of focus. The effect is referred to as bokeh. The more bokeh, the more dramatic the blurring effect. In this article, we will discuss how to control the amount of bokeh in your images.

Getting Started

Being able to control the depth of field is not very easy on lower end cameras as you need to be able to shoot in either an aperture priority mode or in a full manual mode. If you have a fully automatic point and shoot then you will not be able to achieve the effect you want

50mm 1/2500 f/2.8

50mm 1/40 f/22

The setting you need to be able to adjust is the aperture setting, the larger the aperture (the smaller the number) the shorter the focal plane will be. This is one reason that some people buy very fast (larger aperture) lenses. A less expensive lens may have an aperture range of something like f/4.0  -  f/5.6, while you will achieve some bokeh effect with this lens, it will not be as pronounced as it would be if the lens has a f/1.6 – f/2.8.

Without having a lens with a very large aperture, the other way to achieve a dramatic bokeh effect is to use a long zoom lens to shoot very close objects. Since a long lens won’t be able to focus on both something very close and things at a distance, you can achieve a strong bokeh if there is enough separation between the subject and the rest of the image.

225mm 1/800 f/5.6

70mm 1/800 f/5.6

Understanding Aperture

Diagram of decreasing aperture sizes (increasing f-numbers) for “full stop” increments (factor of two aperture area per stop) – Source: Wikipedia

The aperture setting is the size of the opening that is used to let light into the camera and onto the sensor. The size of the opening is measured is F-stops. The confusing part is that the larger the aperture setting, the smaller the hole that will be used to take the picture. The reason why lenses with a very large aperture (smaller f-stop number) are more expensive is because the lenses require more engineering and typically use better and more complicated lens elements. These higher end lenses usually have glass that is manufacturered to higher tolerences and may include special coatings on the glass elements, this helps explain the high costs of the top end lenses.

The other side effect of getting a lens with a small f-stop number is that the smaller the f-stop, the more light will come in per image thus allowing you to shoot in lower light conditions. A lens with a f/1.8 can shoot well exposed pictures in a situation that is much darker than an f/4.0 lens could shoot in.

Why Control DoF?

So now that we know the how of controlling depth of field, let’s talk about why we would want to do this. Isn’t the goal of every picture to have the ultimate tack sharp image? Why would you intentionally blur part of the image? The simple answer is mood. Quite often, the background of an image may be distracting from the subject matter, think of a bride standing in front of a wall of flowers. In this case, the bride is obviously the main subject and anything else may distract from the subject, by blurring out the flowers behind the bride, you can retain some of the color and texture without the detail, adding a much more dramatic feel to the image.

One thing to be aware of is overdoing the bokeh effect. Since the eye is drawn to the lightest parts of an image first, a common problem with a heavy bokeh is creating a large blob of very light color, this can be more distracting to the image than if the background would have been in focus. Used right, the effects can be stunning.

Choosing Lenses

When choosing a new lens, once you decide once you decide the focal range you are looking for, then you go for the lens with the largest aperture (again, lowest number) that you can afford. A common misconception with new photographers is that a lens labeled with a single aperture will only do that aperture. The labeling denotes the maximum aperture at the listed focal length, So if you have a 70-300 f/4.0 – f/5,6, then your maximum aperture at 70mm will be f/4.0 but will shrink to f/5.6 at 300mm. Whereas a 70-200 f/2.8 can maintain f/2.8 throughout the entire focal range but can also go to the minimum aperture of you camera (often f/22 or lower),

Now that you have these basics down, you should be able to tell that the faster (smaller f-stop number) the better able the lens is to shoot in darker conditions and when used at the lens’ maximum aperture, the more pronounced the bokeh effect will be.

Be sure and post some images that you have taken to the Flickr user group and tag them with DoF and cameradojo.

Height

The world does not all exist at an average of five feet to six feet above ground level so why limit your pictures to being shot from that height? Take a look at most model pictures, they are not shot at eye level, most often, the camera is aimed at the model’s chest. Aiming eye level at a person will leave far too much dead space above the head. Experiment with different heights to see how much different an ordinary shot can be when viewed. If you have a baby or small pet, get on the ground and take pictures, try to show the world from their perspective. Look up at objects you normally look down on, look down on objects you normall see from a normal level.

Less is More

Sometimes showing things from different angles can result in an image where less is more. Showing only a part of a common object or a common object from a abnormal angle can really change how you view something. Take the picture here of this slick hot rod, while it does show the car off quite well, the shot is definitly nothing special. On the other hand, if you took some pictures from some different angles or perspectives, you can can really get some interesting shots. Here are some examples of this concept also from this same vehicle.

Pieces & Parts

Just like the previous examples, just showing pieces and parts of something that are even less recognizable than showing something completely obvious like a tire or headlight. Any interesting grill, side louvers, paint job, or some other detail can really make for an interesting photograph.

Again, here are a few examples of this concept:

Here is a gallery of images from The hot Rod Revue at Original Mike’s. These demonstrate the concepts discussed in this article and were inspired by the work of Mike Micklich at Car-tography.com.

Pre-Shoot Checklist
The pre-shoot checklist is the list i use the day before a shoot. This one covers things like making sure batteries are charged, cleaning equipment, and things like that. Nothing is worse than thinking you are totally prepared and realizing your camera battery is near dead when on location.
Pre-Shoot Checklist

Shoot Day Checklist
The shoot day checklist is the list of things I am taking for a particular shoot. Bodies, lenses, filters, flash, tripod, batteries, etc. This is my basic packing list of things that go into whatever kit I am taking.
Shoot Day Checklist

Location Checklist
There are a LOT of logistics about doing location shooting, especially for architecture shots that must be perfect. This list is a ton of questions to make sure you have the answers to such as parking, access, lighting, people, signage, security, etc.
Location Checklist

Wedding Shot Checklist
A wedding is one of the most stressful types of shoots there is, you simply cannot miss a key shot or get a do-over later if a shot doesn’t work. The second part requires skill and experience, but the first part we can address with this wedding shot checklist. Go over this list with the bride and groom and decide which shots are the must-have’s for their wedding. If you don’t want to always be referring to the list when taking the photos, bring an assistant with the list and a clipboard to make sure all the shots were taken.
Wedding Shot Checklist

I hope this inspires you to create your own customized checklists for the type of work that you do so that you will always be as prepared as you can possibly be.

The Image

The shot is an evening shot taken after sunset so there is no visible sun and almost no ambient light. The subject is a girl so she needed to be lit properly which meant artificial light. I also wanted the water to be sharp and not have any motion blur in it.

Making The Image

The light from the sun was almost non-existent so any normal exposure that would freeze the water in mid-air would have resulted in a pitch black background. In order to get any color at all out of the background the shutter speed needed to be 1/15th of a second, now that is one slow shutter! But with that slow of a shutter, why isn’t the water all blurry (not to mention the subject since I shot it hand-held, not with a tripod)? Since there was almost no ambient light, what freezes the subject and the water is not the shutter but the flash. The speed of the flash is about 1/20,000th of a second so it is this short burst of light that, in effect, acts like a fast shutter speed. The flash was a Canon 580 EX II with a 14″ Lumodi Beauty Dish mounted on it about 3′ away from the subject.

The aperture was set at f/8 to provide a wide field of view for all the water as well as the subject and the ISO was at 200 so keep digital noise to a minimum. The flash was fired using a PocketWizard MiniTT1 Transmitter with AC3 ZoneController mounted on a Canon 50D and a PocketWizard FlexTT5 Transceiver on the flash. This combination allowed me to take a few shots and adjust the flash power right from the camera while an assistant held the flash into position.

ISO 200 - f/8 - 1/15th - Handheld

While you may not think you can get a sharp image with a long shutter speed, if flash is the only light source then you can use a very long shutter speed and the light from the flash will be so brief that it will effectively freeze the objects in the frame. This is the same technique for freezing bullets in mid-air and other fast moving objects.

My good friend Chris Diset comes over yesterday and tells me that his significant other Debra has come up with a solution.

Fortunately we all had some of the small Think Tank Photo Pixel Pocket Rockets (for 6 CF cards) laying around that Think Tank Photo had given away in a recent promotion.  The trick here was to cut the separator out of each pocket, this way the gels would be able to fit into the pocket perfectly. This is not the easiest thing in the world to do, you need to be careful as the material in the back of the pockets will tear easily.

Since I use a Large Pixel Pocket Rocket for my CF cards, and its a different color than the small one, this wouldn’t be confusing during the heat of a shoot.

The result is better than I expected as the gels fit absolutely perfect into the pockets. The next decision was how to organize them, and while you may do it differently I figured I would explain how I decided to do it.

The top pocket holds my main color correction gels, this includes the CTO’s (Color Temperature Orange) or the green’s for correcting in fluorescent lighting. This middle pocket holds the color effects gels which is all of the rest of the colored gels. The bottom pocket holds all of the Neutral Density gels. This layout makes it very simple to find the gel you are looking for, and if you happen to drop it in the wind, the gels are not going to go flying everywhere.  This is such a perfect solution for storing gels that I am actually going to encourage Think Tank Photo to offer a version of this pouch like this.

So thanks to Chris and Debra for this awesome quick tip. If you have your own quick tip that you would like to share, please post in the comments section.

Camera Features

First off many people think that all film cameras are probably very difficult to use and all manual. Newer film cameras like a Canon Rebel are just as easy to use as a digital SLR with all the same features like aperture priority, shutter priority, program mode, automatic mode, creative modes, auto-focus lenses, etc. Internal meters make getting your exposure quick and simple and really the only downside is the lack of an LCD on the back.

Older film cameras like the AE-1 lack many of those features. While the AE-1 does have an internal exposure meter, what the meter tells you is what aperture it thinks you should be at for the currently selected shutter speed. The general process for taking an image goes something like this:

1. Set your shutter speed where you think you want it
2. Look through viewfinder at scene and press shutter half-way
3. Find the suggested aperture setting in the meter
4. Look at lens and adjust aperture as needed
5. If you do not have enough aperture to get the shot, adjust shutter speed and go back to step 2
6. Look through viewfinder again and try to get a good focus (no autofocus here)
7. Press shutter
8. Crank film advance

Certainly a little different than how fast we can get a good shot with a modern DSLR.

Rolls 1 and 2

I started off with a roll of color film and a roll of Black and White film. I shot away for two weeks using the camera every so often until the film was used up. I rewound the film and dropped it off at the local lab. The next day I go in to get it and the entire roll was bad. Apparently I hadn’t loaded it right and there wasn’t a single image on either roll. Not to be put off, I grabbed another roll of film on the way out.

Roll 3

Roll 3 was a 36 exposure roll of color film and I made sure to load it right, click off a few frames and make sure the takeup reel was turning with each shot. To kill off the roll I pulled out the camera during a weekend drive-around shoot with my friend Chris Diset. On Monday I dropped off the roll back off at the lab and opted to only have a CD with the images instead of getting prints. The lab told me to come back at 4pm the following day for the images. Day 2, I head over to the lab at 4pm as instructed and get told that their developer machine has died so come back tomorrow. Day 3, I run back to the lab again and am told they had to replace the developer machine and the prints will be done tomorrow. Day 4, back to the lab and this time I get told that they sent the film out because their system was still not back up, but fortunately my film was now back…except that I had ordered a CD and their scanner was down. Day 5 I head back to the lab AGAIN and this time I get my CD of images finally. Back to the studio and load them into Adobe Lightroom.

Of the 36 images, I am pretty happy with 8 of them. Focus is certainly an issue. Its very hard to manually focus in low light and the dimmer shots certainly proved that point. Other images suffered from too short of a depth of field. Overall though, the shots I really wanted to get right did turn out good.

It helps to really know how to use your camera, understand exposure controls and know how shutter and aperture work together. The Canon AE-1 was a serious workhorse and many iconic images from the past were taken with it. The quality of the images is still excellent even if you need to take some extra time to take the shot.

We live in a world of instant gratification and shooting film most certainly does not give you that. Besides the time from shooting to getting the film to the lab, this last experience added four more days to process, really testing my patience.

Is 8 out of 36 a good ratio? Considering what I was shooting, I am going to say yes. Some of the “not keepers” were experiments with some of the lenses I had, so in a since they did turn out. On the next roll there will likely be no experiments and I will be focusing on making each image count.

Oh yes, there will be more rolls dropped off at the lab this year but not to prove a point to anyone, not to be able to call myself a film shooter, and not to be able to say that I can shoot film and other people can’t.  My renewed interest in film, especially on essentially what is a completely manual camera is much more about preserving the craft, continuing to hone my eye for exposure, and teaching myself to slow and make each shot count. At $6 for a roll of film and another $6 in developing each click of the shutter drains about 33 cents from your wallet. This can add up quickly and you certainly want your percentage of keepers to be as high as possible. By pulling out the film camera and having a real cost for each picture, it certainly puts much more value on each shot versus loading up a 16gb CF card and cranking out a few thousand pictures during the course of a wedding.

To Use or Not to Use

The next question is whether or not I will be using film at any weddings or other events this year and I think I actually might. Certainly not as my primary camera but I may drop a single roll at each wedding, engagement, or model shoot. If they turn out, then great, if I blow another roll then I am not out any important images.

Think You Can Do It?

If you don’t have a film camera than I am not going to suggest that you go drop some money on one. You can get a lot of the same experience with your digital camera. Try using some gaffers tape and covering up the LCD on the back on the camera. Bonus points for shooting only in manual mode, and double points for shooting with manual focus. The goal here is to really learn how your camera works and not rely on chimping the result on the back.

If you do experiment with this, please post your results and comment here. I would love to hear what you think of trying it out for a weekend.

But let’s step back in time a little, what about using an older vintage Canon AE-1. There are no scene modes, no automatic modes, no program modes, no eTTL flash, just shutter and aperture and whatever ISO film you have installed.

The Truth Be Told

Even the old AE-1’s had some basic metering and some automatic modes. If you pressed the shutter half-way down, the internal meter would tell you what the recommended aperture setting would be based on your ISO setting and current shutter speed. If you roll the aperture wheel on the lens (yes, on the lens, not on the camera body) from one of the available aperture settings to A, then the camera would set the lens to the recommended aperture setting before taking the shot, thus giving you somewhat of an shutter priority mode (you set the shutter, camera adjust the aperture). Keep in mind this is a reflective light meter so it can sometimes be inaccurate with brighter or lighter subjects.

Is it important that people know how to shoot film?

If you ask most any photography teacher they will tell you that learning film is extremely important in order to understand all of the dynamics of film and that learning the developing process will teach yo….oh man, I can’t even finish explaining it. I think the point that is often missing is not whether someone can shoot film or not, but whether or not someone has the skills and knowledge to get a good exposure without relying on all the modern conveniences of current cameras.

As I discussed this issue with fellow photographers, some felt that it really didn’t matter so long as the person can make good images with what they have. The problem I have with this is that you may be able to make good images, even on a regular basis, what you can’t do is to get a wide range of creative images.

The camera and your flash are going to try to give you a very neutral lit image. While this may be ok a good percentage of the time, when you really want to do some creative lighting your camera is simply not going to know what you want to do.

An example of this is with very dramatic lighting. The image shown here would be almost impossible with any automatic camera or TTL lighting modes. The camera would see the subject as underexposed and try to increase the exposure to give a brighter image. Of course you can usually correct that with flash exposure compensation, but that doesn’t work all the time and if you use most wireless flash triggers you won’t have automatic exposure features anyway.

It’s also fairly common that eventually a photographer decides they want more powerful studio lights, they make a big investment in gear, and then can’t figure out why they are not getting what they want out of them. Again, this is simply a lack of experience in understanding the correlation between aperture, shutter speed, ISO, and lighting power.

If I can help to teach anything, it would be that shooting in manual modes is not as difficult as it may seem at first. Learning how to really control your camera and your lighting will open you up to a whole new world of creativity.

The Accidental Ghost Town - 1/250th - f/5.6 - ISO 50 - 24mm

Some Kind of Bovine - 1/250th - f/4 - ISO 50 - 200mm

Outside of Blythe it was time to take another shot when we tried to get off the road to shoot some wrecked cars. Unfortunately we couldn’t get to the vehicles but the road ended at this small cow stable. In order to make it look bigger than it was, we decided to use a short depth of field by using a wider aperture and a long lens to maximize the effect.

Photo Project 24 Image #1 - Dinosaur in Cabazon

The Image

The image I am starting off with is Sunrise on the Salton Sea which pretty much describes the image pretty well as it was taken just after sunrise on the west bank of the Salton Sea (specifically 20 minutes after sunrise). The sun casts a dramatic reflection all the way across the water while a dead palm tree and the shore line add some additional detail.

Sunrise at the Salton Sea

Making the image

The image itself is fairly simple as there are no extra lights used and virtually no post processing. The image is pretty much as it appeared in camera.

Of course, shooting into the Sun may not be the easiest task unless you have a neutral gradient filter but none was used on this shot. In fact, I didn’t even use optimal camera settings as I had changed them on accident and couldn’t see that I had changed the ISO setting in the viewfinder as I was trying not to go blind from looking at the Sun.

The ISO should have been at 100 but ended up being at 400 and the first attempt was at 1/1600th and f/5.6 and came out pretty overexposed.

1/1600th f/5.6 ISO 400

The second attempt was a little better as I adjusted the settings to f/11 at 1/1600th. This was a pretty good image but the rays on the Sun were not very pronounced and I was picking up too much detail in the foreground.

1/1600th f/11 ISO 400

In order to kill off the detail in the foreground a faster shutter speed was needed so I pushed it to 1/2000th. To pick up more detail from the Sun less aperture was needed so I closed it down to f/22. In Adobe Lightroom just a touch of Vibrance, Setting the Camera Calibration to Camera Standard, and adding a touch of Sharpness where all the post production that was done.

1/2000th f/22 ISO 400

Again the final image and settings show that you can actually shoot straight into the Sun and pull off a nice image without any additional hardware or heavy post processing.

Equipment Used

Camera: Canon 50D

Choosing a Prime Lens

30mm 1/2000th f/2.8 ISO200

If you want a super fast lens or want that really shallow depth of field, a prime lens can be an excellent choice but picking one out from all the different sizes can be a little daunting. Deciding on a lens really depends on what you plan on shooting. Landscape shooters may want a wider field of view, jewelry shooters may want a longer focal length macro lens, and portrait shooters may want something closer to 50mm to avoid any distortion caused by shorter or longer focal lengths. If you are shooting people, I suggest something between 30mm and 70mm. The cheapest lens you can get is the Nikon or Canon “Nifty-Fifty” 50mm f/1.8 which will run you about $99 or so. If you want to try out a prime lens without a large investment, these 50mm lenses offer a nice entry point.

If you are not using a full-frame camera body, then keep in mind your crop factor as it will increase the focal length. On APS-C sized sensor (Canon 30d, 40d, 50d, etc) you have to multiply the lens’ focal length by 1.6 so a 30mm lens becomes 48mm which is almost perfect in terms of distortion. The Sigma 30mm 1.4 EX DC HSM is an excellent choice for portrait and product photographers. This is probably one of my personal favorite lenses due to the size, the light weight, the lack of distortion, the super fast f/1.8 aperture and a cost around $450.

105mm 1/500th f/2.8 ISO800

Moving up in the focal length, once we get out of the common portrait sizes we get into the longer lengths like 100mm. At this length, there is a compression added to the image that can make things look slimmer than normal so it actually can make for a good portrait lens even though many people may not think to use it as one. I like using this lens for small products such as jewelry or things that have a lot of detail.

With the Sigma 105mm f/2.8 EX DG Macro lens not only gives you a nice long focal length but because it can focus at very short distances it can also create images that are life-sized, this is great for close-ups on things with lots of detail such as wedding ring shots.

Hopefully this has given you some insight into why you may want a prime versus a zoom lens and how to go about choosing the lens that is right for you. As you can see, I am not a purest when it comes to lenses and I have been shooting weddings with a Sigma 24-70 DG for several years. Whatever your brand, whatever your need, do your research and figure out which lenses shoot your shooting style, subject matter, and budget.

The following two images show what a little turn of the camera can accomplish.

Straight Shot

Angled Shot

Stop the Madness
So…what is a stop exactly? Simply put, if you take a given amount of light and double it, you are moving up one stop, if you cut the amount of light in half then you have gone down a stop. So a stop isn’t a specific amount of light, instead it is a measure of difference between the amount of light. To be completely technical about it, the term “one f-stop” refers to a factor of √2 (approx. 1.41) change in f-number, which in turn corresponds to a factor of 2 change in light intensity. So how can we visualize this easily? If we have a single light bulb as a base light source, then two light bulbs would increase the light by 1 stop. Going to 4 light bulbs doubles the output again giving us 2 stops, to get to 3 stops we then need 8 light bulbs, etc.

So let’s take the sentence in the introduction, if we wanted to expose one side of the face 1 stop under the other side of the face, what we are saying is we want half the amount of light on the shadow side that we have on the lit side. Pretty simple concept huh?

For the most part, we are actually going to be doing a lot of guesswork unless we have good light meters and can measure each piece of the scene. Using our DSLRs we can zoom into each area of the scene and look at the exposure meter in the camera for a pretty good meter reading as well.

How aperture and shutter affect light
Ok, so now we have a basic understand of what a stop is, now we need to see how to control this using the two basic controls, shutter speed and aperture. To illustrate the effect of aperture, we have created this chart that shows the amount of light that is gathered at typical aperture settings. While each camera/lens may have slightly different available aperture numbers, they are typically in multiples of 1.4 (as described in the previous section). As you increase the f-stop number to the next 1.4 increment, you halve the amount of light.

The effect of shutter speed is the same concept. Every time you double the shutter speed, you decrease the amount of light in half. If you cut the shutter speed in half, you double the amount of light.

Again, you can see this represented by a similar chart.

Where this gets interesting in combining aperture and shutter speed, you can get the same exposure with different combinations of aperture and shutter speed. For example, a shot taken at 1/500 at f/2.8 and a shot taken at 1/60 at f/8 will have the same equivalent amount of brightness, what will change is the depth of field.

Let’s take a look at one of our favorite studio lights, the Westscott TD5 Spidelite. The light head has 5 bulds in it, you can control the center bulb, and two sets of two bulbs. To show how this affects stops we can use the different combinations to control how many stops of light we have:

If we only turn on the center bulb and use that as our base reference point, we can then use the different variations to come up with the following amounts of light changes:

How can we use this information?

If you have a light meter than putting this information to use is just a matter of measure-adjust-repeat until you get the desired light readings you want. With a modern DSLR, we can do this with the camera’s light meter with fairly good results.

Let’s say we want to use a two-light setup to light a subject’s face and we want one side 1 stop darker than the lit side. To begin with we zoom into the lit side of the face (or use the Photovision Digital Calibration target aimed at the light source , the small size works best for this) and adjust the lights until you get a good exposure reading. This is the time to make the camera adjustments to center the exposure in your camera’s meter.

Good Exposure Reading

The next step is to meter the shadow side of the face, using the same technique of zooming into the subject or a target to get a meter reading. This time however we want to underexpose by one stop.

-1 Stop Under Exposed

At this point we now have the camera setup for the right exposure on the lit side of the face and we checked to make sure the shadow side was one stop underexposed, we are now good to take our shots and be confident that the lighting will turn out good.

Summary
Hopefully this has helped to explain the concept of stops as it pertains to the relative amount of light and how we can use the tools we have available to make sure we have good lighting and exposures. To discuss this with others, please join us in our Camera Dojo Flickr Users Group.

Whaaaat, Did he Say Film?

How can anything having to do with shooting film apply to an ultra-modern uber-pixel state-of-the-art modern and very non-film DSLR? When shooting film, you would install whatever ISO speed film and that’s what you were stuck with. The only thing you could adjust is aperture and shutter speed. With a current DSLR we do have the convenience of being able to dynamically adjust the ISO speed. While ISO does play an important role in the overall exposure, we generally do not adjust the ISO simply to increase or decrease or exposure. Instead, ISO Speed should be thought of as a way of getting us into a usable range where the Aperture and Shutter can then work properly, just like changing the film in your camera.

The Exposure L

So let’s look at the Exposure L and see what it is telling us. Along one axis we have the common shutter speeds in one stop increments, along the horizontal axis we have the different aperture settings, also in one stop increments. Now, so long as we are using an ISO Speed setting that will allow us to get a good exposure somewhere on the chart. Once we have a point on the chart that will deliver a good exposure, we can then know exactly what other shutter/aperture combinations will also deliver a correct exposure by drawing a diagonal line between the points as shown on the chart.

For example, if we have a good exposure at f/16 and 1/250th of a second, we can also use the following:

• f/11 & 1/125th
• f/8 & 1/250th
• f/5.6 & 1/500th

By understanding what other aperture / shutter combinations will give us the same exposure, we can then make an artistic choice based on what kind of image style we are trying to create. If we want a shallower depth of field, we can go down a stop, but we have to compensate for moving up a stop in shutter speed.

Only if the scene is too bright or too dark to get an exposure somewhere on our chart do we need to change the ISO Speed setting.

Example Images

If we look at some example images we will be able to see that once we have a usable exposure we can then slide diagonally up or down the chart to maintain that exposure.

Baseline Image settings f/8 1/60th Sec ISO 400

f/5.6 1/125th Sec ISO 400 (+1 stop aperture / -1 stop shutter)

f/4 1/250th Sec ISO 400(+2 stops aperture / -2 stops shutter)

f/2.8 1/500th Sec ISO 400 (+3 stops aperture / -3 stops shutter)

As you can see from the example above, we slide diagonally down the scale so our exposure never changed so long as we adjusted the aperture completely opposite from how we set the shutter speed. As we adjust one up, the other has to go down at the same rate in order to maintain exposure. The effect is that our depth of field gets shallower and shallower as we open up the aperture.

Here is another example using subjects that are further apart.

Baseline Image – f/2.8 1/640th Second ISO 400

f/4 1/320th Second ISO 400 -(-1 stop aperture / +1 stop shutter)

f/5.6 1/160th Second ISO 400 (-2 stops aperture / +2 stops shutter)

f/8 1/80th Second ISO 400 (-3 stops aperture / +3 stops shutter)

In the last sample set we started with a large aperture and as we closed it down to increase our depth of field, we had to slow down the shutter speed accordingly in order to maintain the correct exposure. The only time we need to adjust the ISO is if the scene is too bright or too dark to get a good exposure within the range of settings the camera can handle.

If we look at our Exposure Chart and have shutter speed on one axis and aperture size on another axis, the ISO setting is not another axis like a triangle, it actually is a third dimension which can add or subtract overall brightness to the scene.

Hopefully this makes more sense than all the articles out there that talk about the “Exposure Triangle” because a good exposure does require balance of Shutter and Aperture, but ISO speed is a completely separate variable altogether.

Think about what you will be shooting

On one hand you could make a point for just bringing the most expensive glass you can afford but having a $1,600 lenses that is great for portraits really going to be overkill when shooting landscapes or waterfalls?

For this trip to Maui I knew I would shoot some beaches, water spraying over rocks and lava flows, waterfalls, and maybe some whales. There was going to be very little people shots as we weren’t street walking or hanging around with other people. While the first thing to come to mind would be something like a 12-24mm in order to have a nice wide angle, I know that shooting wide is going to give me a lot of distortion in the image that I won’t want. Since most of the shots are not going to be close up, a 24-70mm would give me less distortion but still give some extra range when needed. For the really long shots I wanted a lens that would give me a good range of focal lengths, hhave a nice long range, but not be too big and bulky. For this lens, I figured a 70-300mm would do the trick nicely.

Which lenses did I go with?

Sigma 24-70mm f/2.8 EX DG HSM

I had the unique opportunity to be able to choose virtually any lenses I wanted to from Sigma and they had two lenses that matched my requirement perfectly.

Short range – wider angle
For the first lens that I wanted for closer shots or wider angle landscapes I went with the Sigma 24-70mm f/2.8 EX DG HSM. This lens is easily on-par with the Canon 24-70 L series lens. While I certainly didn’t need glass this fast during the bright daylight conditions I was shooting in, this certainly made for an excellent walk-around lens that could pull double-duty for shooting landscapes and then be just as at home shooting a wedding or portrait.

Sigma 70-300mm f/4-f/5.6 DG

Long range lens
When I want some range I know I need some long focal lengths but that usually means lugging a very heavy lens around. Again, shooting in great daylight conditions means I have no need for wide open apertures, in fact, probably 95% of the shots I took the entire trip were shot at f/5.6 with some waterfalls being shot at f/11 or f/22 in order to get long shutter times. Since I didn’t need a fast lens, the Sigma 70-300mm f/4-f/5.6 DG would work great. Since I am shooting with a Canon EOS 50D, I have crop factor (or zoom factor) of 1.6 making this actually a 480mm lens! Talk about getting some range with his baby and the optical stabilization helps ensure you get the shot you were aiming for.

Specialty Lenses
I haven’t done the math but well over 95% of the images taken on this were taken with these two lenses. Just to grab some panoramas I did take a 12-24mm and I never go anywhere without my Lensbaby Composer which I used several times with the Fisheye and Super Wide Angle optics.

Summary

The key is to really think about what you will be shooting and under what conditions and plan accordingly. When doing a trip like outs with lots of getting in and out of the car, lots of walking, a few short hikes, and the occasional trail, light weight quickly became a key decision point about what was in the grab bag versus what was stowed in the trunk the majority of the time.

With an accessory flash like a Canon 580 EX II the top piece can rotate around to different angles, this will allow the flash to fire in a different angle than the camera is facing. If you then bounce that light off something like a wall or reflector you can then redirect the light back at your subject to create good directional light. The only thing you have to really watch for is that you are blocking and light directly from the flash to contaminate the scene which can completely diminish the look you are trying to get.

First let’s look at the flash configuration we are going to use. A 580 EX outfitted with Velco and then a Honl Photo Gobo to cover the bottom and right side of the flash head. This blocks direct light from the flash from hitting the subject but still allows some extra light to move up and left which will help add a little fill light. If we used a snoot, we wouldn’t have any extra fill light and the shadows would be much harsher.

The key to this working with such a simple setup is actually having things to bounce the light off of. Without walls and a ceiling that are close enough to effectively use as reflectors we might have to bring in our own reflectors to create the desired effect.

Let’s take another look at the lighting diagram.

The flash is mounted on the camera and is turned towards the wall aimed to hit a midpoint between the camera and the subject. This will illuminate the wall and act like new source of light angled back towards the subject giving us light that appears to come from the right side of the subject. Now let’s look at an example image to see exactly what this looks like.

As you can see, we have effectively created a short light setup by bouncing the light off the wall while also using a small amount of bounce light from surrounding walls and the ceiling to add a small amount of fill light to keep the right side of the subject from being completely black.

The point here is that learning how to use your on-camera flash to behave differently than simply blasting your subject with straight on lighting will open up your ability to create much better images. Experimenting will different distances, angles, and reflector surfaces and soon you will find that you can find useful locations and/or objects to use as your bounce target.

The “Easy Way”
The easy way to get this shot is to shoot the card laying on its side. Once you have the image, take it into Photoshop and rotate it 90 degrees clockwise so it is then standing up, copy a portion of it, rotate it vertically, then add a gradient to fade to white, and viola, you are done. This would certainly have been less time in shot setup but more time in post production. What I wanted was to actually do as much of the shot in-camera as possible, hence, I didn’t do it “The Easy Way” and then “Fix it in Photoshop”.

The Shot Setup
The first thing I needed to get was the reflection under the product. A reflection actually isn’t very hard to do, I do it quite often. I just shoot the product over a sheet of thick plexiglass that is sitting on top of a sheet of white muslin. The image of the product will be reflected into the plexi and you have yourself a sweet reflection.

Getting the card to “stand up” required a little bit of thought. At first I tried some acrylic blocks but that stood out too much and would require more Photoshop work than I wanted to do. The same thing happened with white blocks. The final solution turned out to be super simple. I used a boom arm and suspended the cards using fishing line. With the strobes going off the fishing line just disappeared making touch-ups for real fast.

The Post Production
To get started, the images were imported into Lightroom and the Clarity and Vibrance were bumped a hair, the shots were cropped, and then the Adjustment Brush was used to completely blow out the background. A Foreground to transparent gradient was used to fade the reflection to white so the image would set nicely on a website.

The Results
The final images are exactly what I set out to accomplish with very little post production because I tried to get as much done in-camera as possible. While I could have used Photoshop I often think that it is better to get the shot as close to the finished product as possible when you capture it. By even taking simple shots like this and figuring out how to get the shot a different way is good exercise for when something more complicated comes up. Being able to improvise and come up with creative solutions to problems is a very valuable skill.

Features

As we have already said, the core purpose of DSLR Remote Pro is to allow for tethered shooting. While that seems like a pretty trivial thing, its all of the extra things that DSLR Remote Pro brings to the table.

• Take control of your Canon DSLR camera from your PC (supported models)
• Retain full control from the camera
• Photos automatically downloaded to the PC and displayed in a large preview window
• Large high quality live view display on the  PC with live histogram, autofocus and intuitive manual focusing using mouse wheel with Canon EOS 40D, Canon EOS 50D, Canon EOS 500D/Rebel T1i, Canon EOS 450D/Rebel XSi, Canon EOS 1000D/Rebel XS, Canon EOS 5D Mark II, Canon EOS-1Ds Mark III or Canon EOS-1D Mark III
• Photos are saved on the PC’s hard disk and can also be saved on the memory card in the camera
• Full size preview window can display a critical area of the photo e.g. the eyes and face of your model during a portrait shoot
• Flashing highlight display to highlight over exposed areas
• Grid overlay display for accurate alignment of studio shots. The size and color of the grid is user definable
• Color management and sharpening options for more accurate display of preview images
• Auto bracketing of up to 15 shots ideal for HDR images, interior shots and product photography
• Timed bulb exposures controlled from the PC – ideal for astronomy (Canon EOS-1Ds Mark III, EOS-1D Mark III, EOS 5D Mark II, EOS 40D, EOS 50D, EOS 500D/Rebel T1i, EOS 450D/Rebel XSi and EOS 1000D/Rebel XS only)
• Focus point overlay display for more precise control of auto focus
• Automatic screen blank option – blanks the screen before taking a photo so that the light from the PC display doesn’t affect the subject lighting
• Fullscreen mode for large, uncluttered display of images
• Automatic edit option – automatically loads the image after downloading into the editor or program of your choice
• Automatically stores a short comment in the shooting data of images for easy identification e.g. the person’s name when taking id photos. The comment can also be used for the image filename to make it easier to identify images when taking product shots, school portraits etc.
• Automatically stores IPTC data in images as they are downloaded
• Time-Lapse feature which allows the number of photos in a sequence and the interval between shots to be specified.

Stack it and Bracket

Typically if you want an exposure bracket for HDR images you are limited to the camera’s 3 shot bracket. While three shots is often sufficient, there are times you really want to use more images, with DSLR Remote Pro you can do bracket sequences using either shutter speed or aperture of up to 15 shots. Using tools like PhotoMatix, you can get really incredible results when using larger groups of images.

Another interesting thing you can do with multiple images is called focus stacking. With Focus Stacking you take a series of images of the same object with the focus positioned at different points. When you combine the images you can achieve a super sharp image with a longer depth of field. Photoshop CS4 now has this ability and there are some free tools that can do the processing as well. To use Focus Stacking you actually need a script that will automate some of the steps in DSLR Remote Pro. If you are interested in this functionality, read more about it at http://www.breezesys.com/DSLRRemotePro/focus_stacking.htm.

Live and in Color!

With the newer Canon cameras that support Live View, a whole realm of possibilities is opened up to you since you can display full-screen Live View with a live histogram. The Live View mode also allows you to zoom into the frame at 100% magnification to ensure that your focus is dead on. This is exceptionally useful when doing macro, product, or food photography.

What’s really unique is the ability to do autofocus while in Live View mode. Hitting Ctrl-F will perform a contrast detection routine that may be a little slow but is usually quite good. This however will not work well with moving objects.

Another interesting feature is Onion Skinning. Onion Skinning is a term that is used in animation to be able to see an overlay of the previous image in order to draw a smooth animation. With DSLR Remote Pro in Live View mode you can load in another image or the previous image in order to get precise alignment. This is good for stop motion animation or to accurately align images for panoramas.

Step into my booth

One thing you really wouldn’t expect from a program like this is the Photo Booth mode since there are a handful of companies that make specific photobooth software. With DSLR Remote Pro you can setup a nice photobooth station, even build a whole booth around it, and offer prints right after a series of images are taken. This can be a fun option to offer your clients at different events.

Integrating with Lightroom

Since Adobe Photoshop Lightroom doesn’t have direct tethering ability at this time, the next best thing is to use DSLR Remote Pro and Lightroom together. Lightroom has a feature that allows it to watch a folder and import any files that it sees show up in the folder. This allows you to take full advantage of all of DSLR Remote Pro’s features while having the images go into Lightroom automatically.

Summary

If you want to take tethered shooting to the next level than DSLR Remote Pro is probably worth looking into. The only real downside is that you are limited to the length of cable between the camera and the computer. For $95 you pick up a ton of functionality that the free EOS Utility doesn’t have. For my own studio shooting, I rely heavily on DSLR Remote Pro and as it continues to evolve it just keeps getting better and better.

Goodbye Dust Bunnies

There are three things that I keep handy in order to keep my lenses clean. A good microfiber cloth, a Giottos Rocket Blower, and a LensPen. I do not use any cleaning process that uses chemicals since even the best will leave some residue. Preferably I don’t want to touch the glass at all so the first step is going to be to use the Rocket Blower to get as much off the glass as possible. If something isn’t coming off easily I turn to the brush side of the Lenspen. If the issue is something different like fingerprints (my personal biggest issue) then the best way to clean that is with the felt tip of the Lenspen. The carbon dust will clean and polish the lens to perfection.

The following video will walk through my cleaning process that I go through before any shoot.

What exactly is this colorspace stuff anyway? Basically its the amount of color that is contained in the file when you save it. The three most common colorspaces are Adobe RGB, sRGB, and ProPhoto RGB.  As my friend Rick Miller puts it, you can relate gamut to containers of beer. With sRGB being a 12oz can of beer, Adobe RGB would be a pony keg, and ProPhoto RGB being a full kegger.

The image shown here (courtesy of Cpesacreta) shows the relative sizes of the different colorspaces.

The difficulty here is knowing when to use which colorspace. Who would take a 12 ouncer when they can have a whole keg right? You would think, but the problem is that not all devices can actually display the larger colorspace  which can cause even more problems when it comes to viewing the images, add to that the lack of color management in most applications (like web browsers) and you will often get dull or washed out colors when viewing the images.

Wait a second, huh? If you use a colorspace that allows MORE colors, than why would the images look WORSE when viewing them? The answer that since almost no devices can actually display Adobe RGB, you wind up with an intepretation of the image causing it to look dull.

Effects of Color Space

Does all of this really make a difference? Let’s take a look at some images that were shot in RAW (thus no colorspace recorded on capture) and then saved as both Adobe RGB and sRGB using Adobe Photoshop Lightroom.

Adobe RGB

In all of these cases, the images saved as sRGB should appear more vibrant in Internet Explorer and Firefox since they are not color managed applications. Apple’s Safari browser is supposed to properly display Adobe RGB files and Firefox is supposed to have color management in upcoming versions. However, until everyone is using a browser you should avoid Adobe RGB in order to provide the best images to the widest audience.

What about ProPhoto?

ProPhoto offers the widest gamut of the available common color spaces so should have a place somewhere right? Well yes it does. The best use of the ProPhoto is to use it within your workflow to preserve the largest amount of color in your images and then only do a final conversion to sRGB when saving your images as jpegs.  This is quite easy with Photoshop and Camera Raw while Lightroom uses ProPhoto RGB internally (Geek Note: Actually, Lightroom uses Melissa RGB which uses ProPhoto RGB chromatisity values working in linear gamma, named after Melissa Gaul, one of the Lightroom engineers).

Should you shoot in Adobe RGB or sRGB?

This is another tough question that different people will answer differently. The simple answer is niether. Shoot in RAW and convert to the colorspace you want during your workflow process. If you want to shoot in JPEG then you have to make the choice. The best thing to do is actually experiment with your equipment and software to determine what gives you the best results. Some people think you should shoot in Adobe RGB and then convert to sRGB if the file is for the internet, while others think you should shoot in sRGB so no conversion or translation is applied, thus you should get more accurate color representation.

In the end, you have to make up you own mind as to what works best for you, but you do need to be aware of the differences and some of the issues you can run into based on your choice.

DSLR Sensor

What are you really cleaning?

There are two components that we will look at cleaning, the first being the focusing screen mirror. If you remove your lens and look into your camera with a lens off, you will see a small mirror.  Dust typically doesn’t stick to this surface very much, so a few quick blasts of air from something like a Rocket Blower should keep the mirror in relatively clean and clear.  This mirror, however, only affects what you see through your viewfinder and not what the sensor sees.

The second component is the “sensor”.  To get to the sensor you have to put your camera into sensor cleaning mode which moves the mirror out of the way, letting you get to the sensor plate. It is important to note that we are never actually touching the sensor itself.  The sensor sits behind a thin sheet of glass and it is this glass that we will be cleaning.  Knowing that you are actually going to be cleaning a piece of glass, and not the actual sensor itself, will hopefully make some of you feel a little better about this process.

And for those of you who take your camera bodies to Canon and get a free cleaning whenever you want (like we do), be aware that the days of free cleanings are about over.  Manufacturers are soon going to be discontinuing this free service, from what we have been told.

Lenspen SensorKlear II CCD Sensor Cleaner and SensorKlear Loupe

Tools of the trade

There are many things you can stick into your camera body to wipe down the sensor, but the goal of this article is to show you how to do it right.  There are many, many products available on the market to clean sensors in DSLRs today.  And quite frankly, many of them just don’t make sense.  Recently, we were at PMA in Las Vegas and we saw the myriad of cleaning products and solutions available for this job.  It is both overwhelming and confusing.  Then, we came across a product and a solution that just made perfect sense.  It’s called the Lenspen SensorKlear II CCD Sensor Cleaner and the SensorKlear Loupe.  These two items, together with a blower ball like the Giottos Rocket Blower or the Lenspen Hurricane Blower, make perfect sense as a solution to the problem.

Blowing out the camera

What are we getting into here?

The inside of the camera body is a dark and tight space.  To know what you are getting into, the the SensorKlear loupe is what you use to look into the camera to see if there is any dust that needs to be cleaned off the sensor.  This device is specially engineered to light the interior of the camera body and sensor surface, magnify the view to the eye and allow easy side access to get to the sensor.

There are also two kinds of dust that we will encounter.  Dry dust and sticky dust. Dry dust will make up about 95% of the dust particles you will encounter which is good news since they are easily removed with a blower ball.  A few quick blasts on the mirror, then putting the camera into sensor cleaning mode and then a few quick blasts onto the sensor is usually all you need for the majority of the dust you will encounter.  This should always be your first step when cleaning your camera’s sensor, and many times will be more than enough to solve your problems.  Once you complete this step, either check your sensor with a SensorKlear Loupe or put a lens back on, turn on manual focus and shoot a photo of a white background.  Check to see if there are any spots on your image.

Any dust that remains on our sensor and refuses to budge with just a simple blast of air is known as “sticky dust”.  This dust may be sticky from humidity or it is static charged and wants to just hang on the sensor.  There are several ways to get the sticky dust off and dozens of companies that are ready to sell you all manner of cleaning supplies to solve this problem.  In the worst case, it is possible that a spec might not be so easy to remove.  There are brushes that may work, or sometimes they just end up moving the dust around.  The other products offered are chemicals that will often leave a residue on the sensor glass (and yes, they ALL leave a visible residue… some just less than others).  Depending on the environment, some dust could even have some oil on it and the best you can do with brushes is to move it around and never get it to come off.  That’s when a chemical process and swab may (worst case scenario) have to be used to get that stubborn piece of dust off.

Lenspen SensorKlear

But outside of the worst cases (which RARELY occour), a simple blow, look and swipe should handle all your needs.  This is where the two piece solution of the Lenspen SensorKlear II CCD Sensor Cleaner and the SensorKlear Loupe make the perfect combination.  Let’s get into detail about these two pieces.

The SensorKlear Loupe is an electronically lighted eyepiece that sits over the body where the lens normally sits.  With it’s multiple LED lights, it gives you a wonderful, lighted view of your sensor that is magnified many times.  With this, you can see every spec of dust and debris on your sensor’s surface.  This is the only way we know of today to effectively see what needs to be cleaned.  You simply tell your camera to pup up the mirror for sensor cleaning, remove the lens and lay the camera on its back.  Then, you put the SensorKlear over the body opening and turn on the light.

The Lenspen SensorKlear II CCD Sensor Cleaner is a pen-like device with a hinge in the middle.  It has a capped cleaner surface at one end.  This cleaner surface is a specially designed chamois surface that is shaped like a rounded triangle to allow you to get into the corner of the sensor area and reach any surface.  Unlike brushes that can simply move things around, this pen can wipe just the area where the dust sits and pick it right up.  If the dust is sticky, it will usually pick it up too, or in some cases, it will move it around and turn it from sticky to dry dust, which can just be blown out of the camera.  Either way, there is no form of dust it cannot seem to handle.

Using the SensorKlear Loupe and SensorKlear II CCD Sensor Cleaner

So, the next step is to remove any debris we see.  We are assuming at this point that you have blown out the camera.  With the SensorKlear over the opening, there is a side access opening.  You simple bend the CCD sensor cleaning pen at a slight angle and reach in through this side access opening, watching the whole time throuh the eyepiece.  You make a small wipe or blot of the area where the dust is and it is immediately picked up and swept away.

We know that this sounds like a product plug; and truthfully, it truly is.  This is the first series of products that have actually made us feel comfortable cleaning our own camera sensors.  And that is saying a lot.  As a matter of fact, we heard rumors that Canon service techs themselves use these products for the work that they do on customer’s cameras.  I guess that makes sense to us too.  After all, its the best solution we have seen.

Canon DSLR Hot Shoe

During a wedding shoot one day I noticed that my flash was only firing occasionally. After the initial panic, I quickly figured out that if I held the flash with a little counter-clockwise tension, then the flash worked fine. At the first break, I tried my backup camera and it was doing the same thing. When I got home, I checked it against my daughter’s 20D and it worked fine, and it also seemed that the hot shoe on my cameras was loose compared to hers.Another symptom of this is that the flash will switch from E-TTL mode into TTL mode and the exposure will usually be very overexposed.

After some research on the net, I discovered that this is not an uncommon problem for cameras that get heavy use. Typically, a quick trip to a service center will fix it, but the actual fix is quite simple and you can help ensure that it doesn’t happen again.

What you will need

Protective Plate

The tools needed to make this repair are quite simple, although small. What you will need is a very small flat screwdriver and a VERY small Phillips head screwdriver. A typical cheap set of jeweler’s or eyeglass screwdrivers should do the trick quite nicely.

To make the fix more permanent, you may want to get some mild Loctite or other thread adhesive. I would not use the heavy duty stuff as that is only needed under heavy vibrations and someday, someone may actually need to take your camera apart for service so the more mild version should work perfectly.

You will also want a good clean work area, preferably with a towel underneath everything, if you drop one of the damned-near-microscopic screws you will be in a world of hurt trying to find it in the carpet.

Getting Started

Hot Shoe Removed

I don’t know if this is the same for Nikon or other brands, but I would assume its not too different, if you run into this issue on other cameras, its worth a try before sending it to service.

When you are looking down into the hotshoe, you will not see any screws, they are covered by a removable plate that slides off. This plate is a good thing to have there as on one of my cameras several of the screws were completely backed out and would have been lost if that plate hadn’t been in place.

There is certainly a technique to popping the plate off which is a bit hard to explain but simple once you get the hang of it. The way I do it is to slide the flat screwdriver under the plate coming from the rear of the camera towards the front. You want to be gentle here and not bend the plate, it will come off with very little pressure. With the screwdriver under the plate, the goal is to lift the back of the plate (side closest to the front of the camera) so that a little lip on it clears the bottom section. With a little pressure on the screwdriver to life the backend, and a little pressure on the plate with a finger it should slip out of place slightly. A little wiggling should allow you to pull it the rest of the way out.

Screws Holding Hot Shoe

At this point you will have access to the four small screws that hold the hot shoe connector in place. if you just want to tighten them up, go ahead and do so and skip to the section of reassembling the protective plate. If you want to use a little thread lock, then continue reading.

The cleanest way I have found to remove all four screws without dropping them is to loosen them all up all the way and then place a magnet (I stole one off the fridge). This will allow you to lift the hot shoe connector and all four screws at once. I then clean up the connector and the camera to remove any dust or debris that is there and put the connector back on the camera. If you are using some thread lock, you just need the smallest dot of liquid on the threads, you can do a quick dunk if you have small enough fingers or apply a little to the threads with a toothpick. Put the screws back in and tighten them up.

Putting the plate back on

Plate Rear Hooks

Oh sure, you popped off the protective plate like a pro, did a solid to your camera with a little Loctite, so putting this little piece of spring-steel back into place should be child’s play right? Its actually pretty easy to screw this part up and end up wondering for an hour what the heck you did wrong. Take special note of the picture here showiing how the plate goes back in with the little hoops going DOWN towards the camera. Those little hoops slide into two slots on either side so you have to make sure they are lined up when you push the plate into place and the rear lip slids into place. If you don’t have those two hoops in the right position, removing the plate again to reseat will be an excersize in frustration.

Trust me on this one, I am speaking from experience here. Once the plate is back in place properly, you are all finished and ready to go. If you are using some thread lock, be sure and give it a little time to dry before attaching the flash and torquing the screws, you might end up loosening them before they get glued into place which would really not be a good situation to be in.

At least you now have one thing you can fix if it becomes an issue for you.

It all adds up

If the visual references isn’t quite enough, then another way to think about it is to think of a perfect exposure as the combination of the right proportion of ingredients made up of ISO, Shutter Speed, and Aperture setting. If a perfect exposure = 9, and you have equal parts of Shutter, ISO, and Aperture, then you have a good mix (3+3+3 = 9). If you need to adjust one of the ingredients, then you have to adjust one of the others to come up with the same final number (2+4+3=9), subract from one, you have to add to another to make up the difference. If you have too much of one, without substracting from another, you end up with an overexposed image. Conversly, if you take away from one but don’t add another, you end up with an underexposed image.

The Sunny 16 Example

In a previous article we looked at the sunny 16 rule, this states that on a bright sunny day, a perfect exposure should be f/16, ISO 200, 1/200th of a second. (ISO and shutter are the reciprocal of each other). If we wanted a shallower depth of field and wanted a larger aperture like f/2.8, then since f/2.8 is 5 stops brighter than f/16, we would then need to compensate with either a lower ISO or a faster shutter. Increasing the shutter is the easiest in this example then we need 5 stops of shutter giving us a speed of 1/6400th of a second.

Low Light Adjustments

In low light we have the opposite issue, trying to get enough light into the camera. We only go so slow before we run into blurring issues with slow shutter speeds, and the aperture limit is going to be based on the lens we are using. If we still don’t have a bright enough exposure then we have to compensate by increasing the ISO speed.

Bringing it all together

While each setting can have an effect on the overall image quality, the sum of the three effect the overall exposure. For a refresher on the other settings, be sure and go back through these previous articles:

“Hey Guys,

I got a question for ya. Sorry the answer to this might already be on your site somewhere but I’d just thought I would msg you instead. I was wondering if you had any suggestions for photography books either having to do w/ business or the technical side of things. I’ve read Professional Wedding Photography by damien lovegrove and am in the process of reading understanding exposure bryan peterson. I have fast track photography on order..

Maybe one to do w/ posing??? Its weird I study photography all day long everyday.. but when it comes down to being w/ the couple it’s like I forget everything I ever learned and freeze. Then i want to slap myself because I could have done this or this shot but was having a brief moment of anxiety. I suppose posing and things will come with practice and the more I do it but I really thought I would have the hang of it by now. Any suggestions? ”

Yes Heather, David and I both have a list of suggestions for you.

What is a RAW image?

By RAW, I mean an image that is shot with your camera image quality set to RAW mode which stores the actual sensor data for the scene that was shot. This is different than a JPEG image that is a rendered image of the RAW data that has different effects applied to it by the camera such as sharpening, saturation, and contrast. A good quality JPEG image can look incredibly good and can be printed at large sizes and will look great. A RAW image will need some form of software program to convert the RAW data to something usable. The most popular programs for this today are Lightroom, Photoshop, Aperture, Capture One (Nikon), and Digital Photo Professional (Canon).

Is there a technical difference?

Anyone that tries to tell you there is no difference in image quality between a RAW image and a JPEG is simply mistaken or ill-informed. From a purely technical perspective, a RAW image will always give you a better image. A RAW image simply has more data, for each pixel there is at least twice as much data on older cameras like my 30D and as much as eight times as much data with newer cameras that have more bit depth. This means that a RAW image has the ability to have a greater tonal range than a JPEG. A RAW image will also then have greater latitude than a JPEG image, giving you the ability to process the image to recover shadows and highlights more than you can if you started with the JPEG. Since white balance settings are applied when an image is saved as a JPEG, shooting in RAW will allow you to adjust the white balance during post processing without sacrificing any image data.

This is not an opinion, it is a pure technical fact. So let’s accept that this is true and that RAW has a distinct technical advantage over a JPEG saved from the camera. I don’t think we need to debate that RAW has an inherent technical advantage and I think some people get caught up in this. I think the real issue is whether or not you need the advantages of RAW versus the negative reasons for using RAW that we will look at later.

Getting down with the downside of RAW

The big debate over RAW vs JPEG is whether or not the pros outweigh the cons so let’s look at the cons and see what the downside of using RAW images is:

• Increased file size
  This is probably the biggest issue there is. RAW images are considerably larger files than their corresponding JPEG images. With my 30D, a RAW file will typically be around 5mb while a fine quality JPEG will be around 1.5mb. As the megapixel count goes up, the files get downright huge with RAW images from a new Canon 5D MkII being around 22mb each. If you are shooting lots of images, at a wedding for example, then the larger size of RAW files will be a significant hit. Since the files are larger, they will require more horsepower from your computer to process. For the same number of images, you will need more flash card storage.
• Specialized software needed to process
  If you can call Photoshop, Lightroom, or Aperture specialized software, then yes, you will need something like this or use the software that came with your camera. If you use something other than these programs then you may have issues dealing with RAW files. For a brand new camera, you may have to wait for updated versions of these programs before they can recognize your files. This also means that if your camera is discontinued in the future, there is no guarantee that your camera’s format will always be supported (this is a good reason to use DNG files, but that’s for another article).
• RAW workflow is different than a JPEG workflow
  Is it? If you are already using Aperture, Lightroom, or Adobe Bridge for processing JPEG’s, then there is little to no change in your workflow. Two years ago, before tools like Lightroom and Aperture, working with RAW images was such a pain that RAW was said to mean “really awful workflow”. Since many of us are using Lightroom and Aperture now, there is little to no changes at all for working with RAW files other than they take longer per image to download off a CF card.
• RAW images in third party tools don’t look as good as the JPEGs
  This has been a real serious problem for a while as only the camera manufacturers really have the secret sauce for decoding their RAW images properly. Adobe has pretty much solved this issue with Lightroom 2.2 and the inclusion of camera profiles that setup the RAW processor to match the settings used to create the JPEG images in your camera.

Again, we are looking at facts here and not opinions, but it is important to understand that there is a downside to using RAW files even if I personally feel that the negatives are typically blown a bit out of proportion with the exception of the increased file size which can be a really significant issue for heavy shooters.

The non-destructive workflow

One of the biggest advantages of shooting RAW is that it inherently provides you today with a non-destructive workflow. What it means is that there is no image degradation between saves and any given step in the editing process can be removed. If we are using any of the three most popular tools today (Photoshop, Aperture, or Lightroom) then when we edit a JPEG, and make our changes, those changes are permenant, and because we just re-saved our image as a JPEG some compression has occured, every time we do this we lose some image quality. Sure you can make multiple copies along the way so you can go back to previous versions, but that negates the whole point of JPEG’s saving disk space. I personally work in Lightroom and I can take my RAW images and apply as many edits to them as I want but these changes are simply stored as a set of instructions to Lightroom, thus the original image is never modified. This also allows me to make virtual copies of an image so I can have a color, B&W, Sepia, or dozens of different versions of an image and take up only a trivial amount of disk space since it is only storing the steps to make the changes and isnt storing a new copy of the image itself and again, no matter what I do, there is no image quality lost at all during the post-production process.

Is anyone still using JPEG these days?

If nobody was shooting JPEG anymore than I wouldn’t have so many questions about it but are any real professionals shooting JPEG and the answer is yes.

Carlos Baez is a wedding photographer from Florida, this is someone who makes his living delivering top quality images to high paying clients and yet Carlos shoots JPEG because he can consistently deliver great images without the extra overhead of RAW files. Carlos is an expert at lighting and understanding exposure so he doesn’t rely on post processing to get his images right.

Ken Rockwell is a huge advocate for shooting in JPEG mostly because a lot of people use it as an excuse to not get the image right in camera. Although he has an article about this (http://www.kenrockwell.com/tech/raw.htm). I have posted a link to his article because he does make a few valid points but I think he does go over the top a little on some of the negatives while I do agree that many people use RAW without either knowing why or using it to correct their mistakes from not knowing how to use their camera properly.

Pros against JPEG

It’s only fair that I point out a few pros who have made the switch to RAW and some of their reasons for doing so.

Scarlett Lillian from Florida has been shooting RAW since she started shooting weddings but then tried going to JPEF to save disk and CF card space. After really giving it a try, she finally switched back to RAW because she felt she just wasn’t getting the color and skin tones from the JPEG files that she was when she was using RAW. She uses Photoshop with Bridge as her workflow tool.

David Ziser is, without a doubt, one of the biggest names in wedding photography and recent convert to the RAW side. David’s big switch came when he started using Lightroom for his workflow and then discovered that the images he was getting with Lightroom and RAW files simply gave him a better image than starting with JPEG. David details his experience in a post on his site, although he also make a case for use JPEG for less critical shots that will never be printed at larger than 5×7. Anything destined for the album or enlargements he suggests shooting in RAW and the filler shots can safely be shot in JPEG to conserve space.

Rick Miller who is a Senior Solutions Engineer at Adobe does a segment when he is demoing Lightroom where he shows a picture of his girlfriends dog that is a white curly haired dog. Rick took a picture of the dog that when the rest of the scene is properly exposed, the dog is overexposed. Saved as a JPEG, the details in the dogs fur are completely lost and unrecoverable. The same image shot in RAW is able to use tools like recovery and exposure control to regain all of the detail in the dog’s fur. This demonstrates how even a shot that is technically correct for the rest of the scene may still suffer from being shot in JPEG.

RAW or JPEG – Which is for you?

Since I am far more likely to forget to change my camera from JPEG back to RAW when I need to, I simply leave it on RAW and take the disk space penalty. With a large wedding costing me around 10-12gb of space, it isn’t that big of an issue. If I upgrade this year to a 50D or 5D MkII and I move to having 30-40gb of space per wedding, I may have to rethink this strategy. What I like about shooting RAW for weddings is that in the thick of things, if you do make a small error in exposure or white balance, it is far easier to correct it afterwards. I don’t use this as a crunch, but it is a safety net.

To decide If you should stick with JPEG all you need to do is to take a close look at your images and compare them with what you can get from a product like Lightroom and then decide if your images are good enough or if any improvements that you get from using the RAW image are noticeable and worthwhile.

What do some other photographers say?

Mark Teskey “RAW only. Shooting JPEG is like working without backing up files or a second body/flash. There’s no safety net with JPEG.”

JE Images “RAW all the way. if I need to tweak anything then I have full access to all the info..”

Denise Clay “[I shoot] RAW – I used the best film I could that matched the job in film days, why not do the same now with the best digital file?”

MrsBoesch “I shoot JPG. It takes up less space on my hard drive, and I am of the opinion that you should try to “get it right” the 1st time”

So what are you to make of this?

There is certainly a case to be made that higher quality final images can be made from using RAW files and that shooting in RAW provides a technical safety net (even if you dont need it because you are wicked good). The main issues of working with RAW for me are the non-destructive workflow and the ability to have multiple virtual copies of an image without eating up more disk space. I do believe that almost all of the main complaints about RAW have been more than satisfied with current software leaving the issue of disk space and storage being the only real issue, albeit a signifigant issue for some people.

In the end, the only thing that matters is that you are happy with the images that you are delivering and if you are shooting for clients, that they are happy with the images you are delivering. If you are shooting in JPEG and are happy with your images and you see no compelling reason to switch, then don’t. If someone like Carlos Baez can shoot a wedding in JPEG and he makes a LOT more per wedding than I do, I am not going to tell him he is wrong for shooting in JPEG. On the flip side, if you are shooting in RAW and the disk space is killing you and you are good enough that your images require basically no tweaks for color, white balance, exposure, fill light, highlight recovery, or saturation, then you may be a good candidate for shooting in JPEG. It all comes down to a personal choice. There is no right or wrong answer to this debate, its just a question of what works for you in order for you to deliver the best quality images to your clients.

Have you ever imported some RAW files and when you first open the image in Lightroom the image is vibrant and looks great and then all of a sudden the image switches to something that is less sharp and the colors are all bland? If you have seen this phenomenon, what you are seeing initially is the embedded JPEG image being displayed first and then the on-screen image changes to the RAW sensor data image. The reason why there is a difference is that the JPEG images have had your camera settings applied to them before being saved. With Canon camera, this is usually Standard, Faithful, Landscape , Neutral, and Portrait. Other camera brands have similar types of basic settings. Many people complained that the JPEG image was often very nice and it took a lot of work to get your RAW images to look as good as the JPEG image.

To solve this, Lightroom needed to have a way to understand what the cameras where doing to the images. Initially, you could use the camera calibration controls to dial in some default settings, but this was really inaccurate and rather a pain to use. Shortly after Lightroom 2.0 came out, Adobe came out with the first beta versions of the camera profiles. These profiles were actually based on the characteristics of the different cameras and can be used to very quickly get your image looking better right from the beginning.

Sometimes the effect is more subtle

For some people who still shoot JPEG instead of RAW, one of the complaints about RAW is that it takes longer to process RAW images to get them look good. Lightroom 2.2 with camera profiles solves this problem quite nicely. You can easily create a camera profile preset (or download ours here) and use them as an import preset so that it is applied to every image as you are importing them. Applying the Standard profile during import will get the vast majority of your images looking almost identical to what you would get from saving the image as a JPEG.

Beta Profiles

If you have installed the beta profiles, you can go ahead and remove them using the following instructions specific to your operating system.

Go to the following folder (based on your operation system) and delete anything with the word “Beta” in it’s title. Then restart Lightroom and all should be good in the world again.

While there are a number of other programs available to do HDR with, we are going to look at the three most common ones mentioned in most posts and blogs, these are:

• Adobe Photoshop CS4 – Merge to HDR Function
• Photomatix
• Enfuse

Photoshop CS4

To be completely fair, I am using the different HDR tools here with their default settings and am not doing any additional tweaking afterwards to make the images look better. That being said, the Photoshop result is certainly the worst of the batch. The dark areas are too dark, the bright areas are too bright and it just didn’t do anything to really impress me. I also cannot find any noticeable difference between Photoshop CS3 and Photoshop CS4 in the final output. Even though you could tweak this image in Photoshop, it would be quit a bit of work because you really need to darken the sky and brighten up the building and parking lot. There may be a particular type of image that Photoshop likes better, of perhaps it doesn’t like that the images covered a 4 stop range. If someone has some tips on working with the Photoshop HDR merge, please post them in the comments.

Photomatix

Photomatix is another commercial tool (http://www.hdrsoft.com) that many people consider to be the best HDR tool available. Comparing the images, the Photomatix output most certainly gave the most dynamic range, so much range that it is actually easy to get an image that doesn’t actually look natural. The way Photomatix works is a complete mystery as even in the overexposed image, you can’t see the detail in the windows and doorways of the building the way you can in this Photomatix output. From a “wow” perspective, it is most certainly the most vivid image and has an amazing amount of range, there is almost nothing in the image that is too bright or too dark. While this may be good for some images, if you are trying to replicate what you are seeing with your eye, this isn’t quite accurate. Is it stunning in it’s range? Absolutely, no question there, it wins hands down in that area.

Enfuse

Enfuse is a different type of tool that compares multiple images and chooses to keep the pixels it feels are the best exposed. Using Enfuse by itself can also be an exercise in frustration. To simply using Enfuse, I use LR/Enfuse from Timothy Armes (http://timothyarmes.com/lrenfuse.php) which integrates into Adobe Photoshop Lightroom. Using just the default settings, the result is an image that is much more natural and is truer to what you would see with your eye. A big advantage of using Enfuse (especially with LR/Enfuse) is that it is significantly faster than Photomatix, the downside is that you don’t get the amazing results that you can get from Photomatix. Enfuse is going to give you a far more natural look.

Summary

It’s not entirely clear if these is a real no-brainer choice between Photomatix and Enfuse as it is really dependant on what you are trying to accomplish with the final image. Photomatix can certainly deliver outstanding images that are virtually impossible to achieve any other way and can also create more natural looking results by toning down the resulting image making it a more versatile tool overall. Enfuse has its advantage in being fast and easy to use when integrated into Lightroom and will create very nice, natural looking results, and if that is your goal then sending a few bucks to Timothy for LR/Enfuse is well worth it. Personally, I have both installed and will choose when to use each tool based on what result I am looking for, and knowing the strengths and weaknesses of each option will make it easier for me to decide when to use which tool.

What is this aperture thingy anyway?

Inside each lens is a diaphragm that can open and close, the size of the opening at any given setting is what we refer to as the aperture setting. On our cameras we refer to specific size settings as f-stops such as f/2.8, f/5.6, f/11, etc. While the obvious value of adjusting the aperture is to control how much light enters the camera, there is a secret hidden world beneath the hood that we will need to get a grasp of as well, but let’s start at the basics first.

For a given ISO setting and shutter speed we can adjust the amount of light entering the camera by adjusting the aperture, a smaller diameter (higher f-stop value) will allow less light in, while a larger aperture (smaller f-stop number) will allow more light it. If we refer to the Sunny 16 rule, we know that on a bright sunny day, if we are using ISO 200 and a shutter speed of 1/200^th then we will get a good exposure at f/16. As the sun goes down and there is less light, we need to allow more light into the camera, we can do this by opening the aperture up (again, using a smaller number) to allow more light in. This sounds easy enough right?

Image showing relative sizes of aperture

If that is all there is to it, then this whole aperture thingy would be a piece of cake and life would be good. It is enough to get you going into how aperture plays a role in getting a good exposure, so it is certainly a lesson worth learning and understanding well.

Have you collimated your rays lately?

The opening of the diaphragm also will control cone angle of light coming into the camera and this is why adjusting the aperture can affect the depth of field. To see how this works use your thumb and pointer finger to make a big circle, with one eye closed look through that at a finger on your other hand held about 12″ away. This is going to simulate a large aperture, you will be able to focus on the finger but you will have far less focus on something across the room. Next, make the circle very small and look through it again (now simulating a small aperture), you will be able to focus on both your finger and something across the room equally well. The reason for this has to do with the angle of light coming into your eye, with the large circle, light is able to come in very straight which creates a shorter focal plane, with a smaller aperture opening the light comes in as a cone shape giving a longer focal plane. While this simple experiment has a very subtle effect (not everyone may even notice it working) in your camera it can have a dramatic effect on how your images look.

Factors that determine depth of field

There are three factors that will determine the amount of depth of field you will have in your image, and taking from a comment post from Photo Larry, this points out the different factors:

In a comment from an earlier post, Photo Larry provided this very simple guide:

• Distance from the subject (Close=shallow, Far=Deep)
• Focal Length (Short=Deep, Long=Shallow)
• Aperture (Small=Deep, Open=Shallow)

Aperture Setting
We have already covered this one, the larger the opening (smaller f-stop number) the shorter the depth of field will be.

Focal Length
The longer the focal length the shorter the depth of field will be. This is why you will get more blurring effect on telephoto lenses than you will with wide angle lenses. The most popular portrait lens is the 70-200 f /2.8 because as you back up from the subject and use the longer focal length with a large aperture the more the background will get blurred out.

Distance to Subject
The further you are away from the subject, the more depth of field you will have as well. This is much easier to see with a long telephoto lens, if you focus on something very close to you, much of the background will be blurry, as you focus on things further away less of the foreground and background will be blurry.

Two images with different aperture settings

Summary

Hopefully this will help you understand the basics of what your aperture setting can do for you and how to begin to use it to your advantage both in getting enough light into your camera and by being able to add some extra flair to your images using the depth of field.

Real and fake SanDisk Ultra II CF cards

The first fake CF card I came across was pretty obvious, visually. I received it with a used camera I bought, so I really couldn’t complain. It was basically free and I was thrilled at the time (2006) to have a 2GB card thrown in with a camera. But it was the performance of the cart that tipped me off to the real problem. The card was significantly slower in the writes than my other SanDisk Ultra II cards; about half the write speed or worse. Here is a look at the fake card next to the real card (right):

Back of 2GB SanDisk Elite CF cards

It is pretty obvious here which is the fake card. Come on, counterfeiters, can’t you do a better fake label than that? As I read up more, it seems that the early cards were easier to detect. Not only were the front stickers obvious, but the rear stickers were missing a lot of telling information. There were no serial numbers on the fake card. This was the first give-away. There was really not much of anything specifically identifying the card on the back label of the fake card. Notice that the real card on the left had the SDCFH identifier, as well as the patent numbers. This would be easy enough to fake too, if they weren’t so lazy. (right):

Close-up of real & fake SanDisk Ultra II CF cards

When you zoom in close (these images were made on a cheapo flatbed scanner at 1200DPI), you can also see the difference in the grain of the plastic. The fake card has a rougher texture and surface on it than the real SanDisk card. On closer inspection, you can see that the grain in the printing is finer on the real SanDisk card also. But these differences alone are harder to distinguish with the naked eye. If the labels were better duplicated overall, you might not even notice such small details as those. You can click to enlarge the photos to the right and get a better, more detailed blow-up of these differences. (right):

Sides of SanDisk Ultra CF cards

But here is one place that they did get clever… the serial numbering. Notice how close the printing is on both of the cards? Without contacting SanDisk, there is no way to tell which one is real and which one is a fake. (right):

So, recently I decided that it was time to buy me a new, 8GB SanDisk Ultra IV compact Flash card as my Canon 1DS Mark III burns through a lot of space at around 25MB per image. 2GB and 4GB cards were just not enough for events. I decided again to test my luck with a new SanDisk Ultra Card, and thought I would try to save a few bucks on ebay. What the heck… if the owner says it comes new in the box, that’s a pretty good sign, right? And sellers in Hong Kong can have real product once in a while too, right? Especially if it is in the new, retail box? And since it is not from the U.S., it could be cheaper, right? Like half price?

O.K., I have to say that right off the bat the first signs of trouble are right here. Half price, easily duplicated product from Hong Kong is a sure sign of fake product on ebay these days. However, for $29.97 shipped, it was worth it to see how good they really are.

Fake SanDisk Extreme package

Here is what I received, in a padded envelope from Hong Kong, partially crushed (right). Surprisingly, the box looks very very real. The gold foils are vibrant and shiny, the texture of the box is identical. And inside the box was the card in a plastic holder, a SanDisk keychain card holder and an SanDIsk RescuePRO 4.0″ installation CD. Pretty much every detail of the real box and contents was duplicated here with extreme care, and with only minor differences. At first glance, I was fairly convinced that this was actually real, or was it just a really damn good knock-off. After closer inspection, it seems that the later was the case. How could someone afford to go to all of this trouble?  Was there really that much profit in selling a $70 card for $30 on eBay with all of these production costs?

Real and fake SanDisk Extreme CF boxes

Looking at the box itself side by side with the real thing, it is hard to see many differences. The boxes look identical from the front, outside of the print color being a little off at the bottom (which is much more apparent in these photos and to the eye). Producing boxes like this with the gold embossing is not cheap process. Either these are the real thing, or someone is mass producing these to keep the costs down. I fear at this point that the compact flash counterfeiting business is not a small one. Someone is investing a lot of money into fake product and fake packaging here.

Back of SanDisk boxes

The back of the box is a bit different too. That would be the next clue on first, unopened inspection of the box. The real SanDisk IV box is the one on the left with a lot more text on it.  I only have 4 SanDisk Extreme IV boxes in my office (real ones).  The boxes for my SanDisk Extreme III cards are in storage, so I cannot see how much the back of the boxes changed from the III series to the IV series, but I assume that all boxes of series IV cards are pretty much the same.  This makes these changes on the back of the card more suspicious.

Real SanDisk Exreme Box

Fake SanDisk Extreme box

Now let’s look at a real box and content next to the fake box and content. They both have the same sleeve and slide-out insert format. They both have the same inside plastic housing and clear cover. They both have manuals, a CF hard plastic case and mini CD with software on them. They even both have a keychain CF card holder, although the real one has red text on it and the fake one white text.  The only piece missing from the fake packaging is a small advertising insert.

Real and fake SanDisk manuals

The manuals/documentation are slightly different.  The fake manual (on the right) is printed on cheaper paper with a much yellower cast to it.  The print quality is slightly lower than the original, real documentation pamphlet.  Interestingly, my real documentation is in Spanish, even though it was bought right here in the U.S. from an authorized SanDisk dealer (samys.com),   Notice the difference in phone numbers? I tried calling the number on the fake document and it rings SanDisk.  The phone number on the real pamphlet… wrong number/disconnected.  Now that’s funny.

Bottom of SanDisk boxes

On closer look at the bottom of the boxes you can see a numeric difference with the 8.0GB box. The real 2.0GB box has a part number of SDCFX4-2048-901. I assume that the 2048 is for 2,048MB, or 2GB. The 8.0GB fake box has a part number of SDCFX4-4096-904. Would that not be the part number of a 4,096MB card, or a 4GB? In an internet search for SDCFX4-4096, it seems it is the part number for the SanDisk Ultra IV 4.0GB compact flash card. There is our first clue.

8GB Fake SanDisk Ultra IV CF card

But, once we take out the CF card and begin to examine it, the details start to appear. The first thing I noticed was that it looked very close in all aspects to a real card. “Hmmm… maybe this is a real SanDisk Extreme IV.” Even the bottom edge of the card has a full serial number and ‘Made in China’ perfectly stenciled onto the case.

In further examination, I started to notice that the label was on crooked. But hey, that could be an issue in assembly that could randomly happen, right? Then, as the light caught it right, I also noticed two bubbles in the front label sticker. “Hmmm… this is getting more suspicious. SanDisk usually doesn’t let these kind of flaws through. This must be a hand-applied label.” Also notice that the corners of the label are square and not slightly rounded. This is another sign of a shortcut in the die cutting process of the fake label. On even further examination, you can see that the outer plastic edged of the card is different – different plastic to metal widths in the edges of the card.

8GB real vs fake SanDisk Extreme IV CF cards

The next thing I noticed is an issue which began to appear in several other articles, is that the holographic background to the lettering scans as a blue tint, and not gold like all of my other SanDisk Extreme cards. In this image (right), you will see that the fake card on the right has a blue tint to the lettering and the real card on the left appears more gold. Some of the elements are a little different size (like the E.S.P. logo), but overall it’s a pretty decent copy label sticker copy.

8GB real vs fake SanDisk Ultra IV CF cards

Next, lets look at the back of the cards. Again, the card on the left is the real card and the one on the right is the fake. Notice how it is a little dingy looking? That’s about the only difference on the back side. Even the corners of this dingy white label are rounded. It is hard to tell from the back side what makes this one fake, outside of the off-white paper used in making the label.  Again, a lot of work to make a fake card.  We are almost seeing efforts on the level of paper money counterfeiting here with all of the attention to detail in the print work.  Isn’t that another scary issue we have been reading about these past few years coming from China?

6 different CF cards

O.K., looks aside, its time to get down to the real meat of this.  How does the fake card perform in comparison to the real SanDisk Extreme IV cards?  To start, I do not have a real 8GB SanDisk Extreme IV card to test against, but I do have many 2.0GB Extreme IV cards that I bought from an authorized dealer.  This should be fine for our tests as the complete series of SanDisk Extreme IV cards are expected to perform similar to each other, within a small margin of error.  I also decided to throw in a few other generic and non-generic cards for comparison, and I included 2 separate SanDisk Extreme IV 2.0GB cards in the test to make sure that the real SanDisk IV cards perform equally in all aspects. You can see all of the cards (except for a 4.0GB PhotoFast Super card that looks identical to the 2.0GB Fotofast Super card) all in the image to the right.  The results are absolutely fascinating.

The test machine is a Mac Pro tower, 8 Core 3.0GHz Intel Xenon processors, 12GB RAM, Seagate 750GB SATA drive, Mac OS X v10.5.5 and a DELL 30″ monitor with 9in1 USB2 card reader built into it.  These specs are really irrelevant as every read and write was done with the same hardware and data.  That part is equal throughout the test.

The read/write copies were done with a folder containing ~1,000 jpg image files, 500k to 4.5MB each in size, 1.83GB (1,949,350,680 kbytes) total in size. 2 identical reads and writes were performed with this folder of images on each cards to insure consistency. All results were rounded to the nearest second. Margin of error is +/- 1.0 second.

Sandisk cards compared

This first chart is of read and write times for this folder of information to just the SanDisk cards, both real and fake. Notice how the read times are all pretty close, with the real SanDisk Extreme III and IV cards being almost identical, and how far off the 8.0GB fake card is from the others.  This is your first solid confirmation that you did not get what you paid for.  When you buy a card of this class and price, you are paying for speed, quality of build and the reputation of the company standing behind it.  This card is dropping the ball on all of those factors.  Below are the actual numbers from the tests.

All CF cards compared

Now, let’s throw some other cheapo cards into the mix.  The first is a Kingston Elite Pro 50X CF card (not necessarily a cheapo) and the other two are FastFoto Super CF cards, 2.0GB and 4.0GB.  These cards were bought 2 years ago off of an online discount house having a sale.  The interesting thing here is that these cards are really out of whack when it comes to write speeds, but their read speeds are good.  These were really cheap at the time I purchased them, and now you can see why.  However, the fake SanDisk 8.0GB cards are not terrible by comparison to the 2 year old generic CF cards. Below are the actual numbers from the tests.

SanDisk and fake CF cards

So, taking the data from the test and calculating MB/sec, we can see the relative performance each of these cards attains.  Let’s start with just the SanDisk cards and the fake SanDisk card.  Below are the actual numbers from the tests.

Transfer rate of all cards

Here is a comparison of all of the cards for transfer rate in MB/sec.  Below are the actual numbers from the tests.

A note to SanDisk:  Please forgive me for straying from authorized dealers just this one time.  The economy is rough, especially for those of us in photography.  The price was just too tempting.  I have purchased over 10 authentic cards from authorized SanDisk dealers in the past.  I promise not to stray again.  I offer this article to help others not stray either as a peace offering to you.

First off you need to realize that studio flashes like the PhotoBasics StrobeLites are not automatic like the on-board or accessory flash on your camera. A studio light doesn’t know what you are trying to do and will not adjust itself for the camera settings you have dialed in. You also need a means of firing the lights off when you press the shutter, all that and more will be covered in this article.

Connecting the lights to your camera

PC Sync port on Canon 30D

The first thing we need to do is to connect the lights to your camera, for this we are going to need what is called a PC Sync port. On most Canon DSLR’s the PC Sync port is on the left side of the camera under a rubber flap. In the image here you can see the PC Sync port and the end of a PC Sync cable. In my typical setup I will have the main light plugged into the PC Sync port to fire it and the other lights will automatically fire at the same time because they have a built-in optical slave that will fire the flash when another flash is detected. Since this happens far faster then the mechanical shutter, the effect is that all of the lights fire at exactly the same. There is a limit of how fast the lights will sync to the camera but we will address that in a moment.

Weim Hot Shoe Adapter

If you are unlucky enough to not have a PC Sync port on your camera then you will need to purchase a hot shoe adapter. The recommended one is the Weim Hot Shoe Adapter which sells for about $50 at most places. This will got into your camera’s hot shoe (when an acessory flash plugs in) and has a PC Sync output port on it.

As I mentioned, the lights do have an optical slave so they will fire when another flash is used so you may think you can just use the flash that is built into your camera to fire off the big lights. While this will work to an extent, the problem is that unless you know how to adjust your flash’s output compensation, the flash is going to fire at a level that your camera expects will be correct for the given light, when the big lights fire along with the built-in flash, your subject will no be over-lit and the scene becomes overexposed.

Rear view of StrobeLite

The opposite end of the PC Sync cord plugs into the back of the light. In this image you can see the 1/8th inch mini plug port on the bottom right hand area of the strobe head. With the camera and the lights connected, you are all ready to take some amazing images right?

If ONLY it was that easy. Now actually comes the hard part, figuring out how to get the light set right for a proper exposure. Hang in there, it won’t hurt too much.

Getting the lighting right

Output Adjustment Dial

Nice, quality studio lights make your lighting easier right? I wish! In the last section I explained that your on-board or accessory flash will meter the scene and use the appropriate output for the exposure metering, not so with studio lights, at this point you are full manual.

On the flash will be an adjust dial to control the amount of light output. On the StrobeLites this goes from full power down to 1/4 power given you two stops of light output control. If you have a light meter and know how to use it, you have all the tools you need to get the shot right the first time. If you don’t have a light meter then you will need to continue reading.

Since I shoot with he same lights, in the same studio, with the same basic setup the vast majority of the time I know the basic light setup that will work without have to take too many test shots, I can usually get it dialed in within about three shots.  A key thing to note is that your meter in your camera is basically worthless at this point. You are going to want to shoot in manual mode otherwise the camera is going to try to adjust your settings for the metered light. In manual mode you have total control. So where should you start?

For most of my pictures I start with the following basic settings:

ISO: 200
f/Stop: 11
Shutter Speed: 1/200th second

In fact, those are the exact settings I used for the previous pictures in this article so far. Why these particular settings? For one, I like shooting at ISO 200, I like the results I get at that speed, f/11 is my normal aperture setting unless I am going for a particular depth of field effect. That leaves two ways to adjust the amount of light I need. I can either adjust the shutter speed or adjust the light output of the flash. You may think that you may want to go with a faster shutter speed to make sure you dont introduce any camera blur but in most cases you can’t shoot any faster than 1/200th or 1/250th depending on your lights/camera combination. With the PhotoBasics StrobeLites and a Canon 30D, I have never had an issue at 1/250th but I like the extra margin of safety of using 1/200th. Let’s take a look at what happens if you shoot faster.

Out of Sync Image

The image shown here was shot at 1/640th of a second, while this would be perfect safe if I was using the Canon 580 EX flash, the StrobeLites cannot sync with the camera at that speed so what happens is that the strobe went off too late causing the image to be partially cutoff by the closing of the shutter mechanism. Because of this issue we are limited to speeds of 1/200th or less so I usually will stick it at 1/200th and be done. That leaves adjust the light output higher if I need more light or using a lower output or a slower shutter speed if I need less light. Knowing that the only things I will need to adjust are my light output or shutter speed I have really reduced my possible settings from a handful down to basically one, and its either shutter speed or light output.

Since most of my shots are product shots, the lights are generally pretty close to the objects so I will start at a very low power output of the flash, if its too bright at the lowest setting and I am already at 1/200th of a second the only way to cut down on the light being captured is to move to a smaller aperture setting like f/22. If the light isn’t enough I can just reach up and dial in more light or use a slower shutter speed.

With a little practice and a handful of confidence, you will be getting your lighting dialed in within a few shots. Take your picture and then look at the histogram of the image on your LCD of your camera to double-check the exposure. If its too dark, bump up the light, if its clipped out, dial down the light. Nothing will beat just a bunch of practice with your own lights/camera/lenses/environment to get you familair with how your lighting setup will work the best and soon you too will be able to get it dialed in perfectly within just a few quick test shots.
