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.

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 two most common issues are not being able to get the background color bright enough or the background color gets too washed out. Let’s get right into it and see how we can improve our technique and use colored gels for our backgrounds more effectively.

The Setup

The setup is very important to make sure everything goes smooth. First off, I prefer using a black seamless paper for the background. Black paper will result in more vibrant colors where a white background will make the colors look duller.

Secondly, you need to make sure that your lights that are lighting your subject are not hitting the background which will cause the colors to wash out as well. The two ways to do this is to use more side-lighting and to increase the distance between the subject and the background. The other advantage of increasing the distance between the subject and the background is that you will be less likely to get color spill on your subject from the background light.

Getting The Exposure

Probably the biggest mistake people make when learning to use gels is to get the lighting for the subject all setup and then try to dial in the background. If you do this in the opposite direction you will get where you want much faster. The following are the three images I took in order to get my light dialed in.

Initial Background Shot

In the initial background shot you can see that I had no light turned on the subject. The background wasn’t quite bright enough so I needed to power up the background flash another stop.

Subject Lighting Test

in the first lighting test with the subject light, the background is nice and bright from turning the power up, but the subject is still underexposed by about a stop so the main flash needed to be powered up more.

Final Shot

In the final shot we have enough light on the subject which is coming from about a 45 degree angle to camera-right and using a Large Rouge Flashbender to flag the light from hitting the background giving me exactly what I needed to get the shot.

The final settings are as follows:

Main Flash: 1/8 Power
Background Flash: 1/8 Power
ISO: 200
Aperture: f/5.6
Shutter: 1/250th

Be sure and experiment with gels and see what you can come up with and be sure and share your images with us.

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.

The plugin we will use is Timothy Armes’ LR2/Mogrify which uses ImageMajick to do things such as:

• Graphic watermarking
• Multiple text annotations
• Multiple borders
• Image resizing
• Adjust saturation and brightness
• Export against an ICC profile file

How much does this amazing plug-in cost? Well, it is free if you want to be limited to only exporting 10 images at a time. If you need to do more, than Timothy will accept any donation that you think is fair.

Installation
First off, we need to download LR2/Mogrify from Timothy Armes site at:

http://timothyarmes.com/lr2mogrify.php

Follow the installation instructions there for either Windows or Mac OSX. I won’t cover the installation since it is only a few simple steps.

Usage
Using LR2/Mogrify is as simple as using Lightroom’s existing Export function as the functions are added into the export utility. The easiest way to get things started is to create a new file in Photoshop with an empty (transparent) background and your logo on other layers. If you don’t have Photoshop, anything that can create a PNG or GIF with a transparent background will work.

From the Library module in Lightroom, select an image or images (up to 10 with the free version) and click on the Export button.

In the Post-Process actions enable the features you want like borders, or Graphical Watermark. In our case we will select the Graphic Watermark, select the file that we want to use, select the bottom left hand corner of the image, and resize the image if needed.

After you configure all the settings you want, click on the Export button to start the process. In a few seconds you have created your first watermarked images.

Here are a few images showing some different watermark styles as well as a multi-line border setup.

Who would have thought that doing advanced watermarking would be this easy? Please consider donating to Timothy for his hard work on bringing us a tool that provides the functionality that should have been included in Lightroom.

Below is a video showing exactly how this works:

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.

I have been a fan of Wolverine products for almost four years now and my trusty Wolverine FlashPac was in need of an upgrade. Not that the FlashPac didn’t do it’s job, its just that it was pretty slow and didn’t have a display that could be used to view the images. Without hesitation I turned back to Wolverine to see what they had available and I found the new ESP Digital Photo Album and Multimedia Player. While the full name may be a bit long, it does convey a lot more of the ESP’s features as well as being a card reader, external hard drive, and FM radio.

Overview
The ESP is an incredible multimedia device that can handle most all of your portable multimedia needs from listening to MP3′s, watching videos, playing a photo slideshow, or listening to FM radio. While many people will love all of those features, from a photographers point of view the most important things to me are the ability to do backups of my compact flash cards in the field, review the pictures on the device, and to have a portable device to show potential clients a slideshow of my work. The ESP does all of these tasks quite well and at a price that won’t make you wonder why you didn’t just buy a nice laptop instead.

Features
As already mentioned the ESP has a multi-function card reader that can either make backups to the internal hard drive of the ESP or when connected to your computer’s USB port your cards will appear of drives that you can access directly.

Setup
The setup of the ESP is quite simple, it comes with both an AC adapter and a USB cable, be sure and plug it in until fully charged before using it the first time, after that the simple to navigate menu system walks you through everything you need to know.

“The ESP was a lifesaver for us at a fashion shoot when the assistant left the CF cards back in the car. With the ESP we would fill up a card, tell everyone to take a five minute break, dump the cards to the ESP and get right back to shooting.” – David , Esquire Photography

ESP Controls

Usage
The ESP’s operating system is very simple to use and works the way I would expect it to, when I insert a card it pops up and asks me what I want to do with it, I select backup and it just starts working. The main controls consist of the “joystick”, a menu button, and the ESC button.

Using just these three simple controls you can manage everything on the system. The “-” and “+” buttons control volume. The only other control is the power button on the right side as well as a lock control to keep the power from coming on accidentally.

At the bottom you can see a small mic port for doing audio notes and near the top are the LED indicator lights.

The has an optional docking station that can also be used for capturing video and audio from remote devices. Since I don’t have a use for that right now I didn’t get one yet to see how that works.

ESP Menu System

The menu system is an icon driven system with easy-to-read captions to help you navigate. Pushing left/right or up/down on the directional pad will move you from application to application and then pushing in will select the item. The Menu key will give you a list of available options from wherever you are while the ESC key will back you out one step at a time.

The main thing to keep in mind is that images that are backed up from a memory card are found in the Backup application instead of the Pictures application. You have to specifically copy images into the Pictures folder for them to be viewed there. This is a great way of having a photo slideshow of images without getting confused as to what images are from your current photo shoot.

What I actually like to do is to backup my images to the ESP and then if I have time, review them for focus issues or just for being a bad image, I can delete them right from the ESP and save time later when importing the images into my computer.

ESP playing video

For client meetings, I also created a couple of really nice slideshows using Proshow Gold and output them formatted properly for the ESP. Let me tell you, the image shown here does not do the ESP justice, the screen may only be 320×240 but the slideshows and pictures look fantastic on it. So far, everyone that has seen the slideshow videos on the ESP have been very impressed.

The ESP has a bunch of other features that I could spend a few more pages writing about but they really don’t have much appeal to me, these include the mp3 player, the FM radio, the audio recorder, and the Tetris-like game that is included. While those are nice add-ons, they really aren’t the main reason a photographer is going to want the ESP.

Why the ESP?
Why would I choose the Wolverine ESP over the Epson P-5000? The simple answer is a cost/benefit analysis blows the Epson out of the running. For almost twice the price of the Wolverine ESP, the Epson P-5000 offers basically a nicer screen. When the folks at Wolverine decided to make a new device, they interviewed tons of photographers and asked them what they would like to see that would compete against the Epson units and the top answer was that they wanted a much more affordable device even if it meant having a lower resolution LCD display.  If I am going to spend $800 for a portable media device, its going to be a new laptop, not a small box I throw into my camera bag and use mostly as an external drive and card reader. Coming in at $329, the ESP is much more affordable and does it’s job exceptionally well. It’s a nice upgrade from my old FlashPac in terms of functions and download speeds which is a nice bonus as well.

What’s in the box
In the box you will find the ESP unit itself along with the nice quality carrying case along with the user documentation and CD, AC charger, USB cable, Audio/Video cable (to connect to TV), and Earphone.

Summary
The Wolverine ESP competes nicely against other units offering similar features and at a price that doesn’t give you sticker shock. The base features do exactly what they are supposed to do while there are enough extras to add even more value to the package. I don’t leave for a shoot without my ESP in my bag and often will be making my backups of my cards on the drive home. With my old Flashpac I would have to be quite far away to actually finish a large backup on the drive home but now it takes a fraction of the time.

Summary
The FX is a colored gel system that comes with five colored gels (blue, green, red, yellow, and amber) and a gel holder that attaches to your flash with velcro. The kit contains the holder, the five gels, a carrying case, and velcro pads. The FX is available at most camera shops or online for around $35.00.

Usage
The FX attaches via velco to your flash with the included velcro pads. If you are like me and use a variety of modifiers, putting some velcro pads on the flash really isn’t an option. Instead of sticking the velcro pads on, I use a Honl Photo Speed Strap and the FX attaches to the Speed Strap quite nicely.

To use, pick out a color you want and insert it into the FX holder, attach the holder to your flash and you are ready to go. Keep in mind you are going to lose about 1 stop of light when using the gels so adjust your flash accordingly.

Shown here is the FX attached to a Canon 580 EX II and fired at a black muslin wall so you can get a feel for how to use the system. At first you may think you want to aim the colored light at a white wall for the best reflection, but in fact, the opposite is true. A white wall or white seamless paper will reflect the light and just give you white instead of the color you want. Using a dark grey or black background such as seamless paper, black muslin, or black velvet will give you the best effect.

By adjusting the output of the flash you can control the brightness of the background and adjusting the position can create a gradient effect as you can see that the color goes from brighter “sweet spot” to darker edges.

“The Lumiquest FX is going to be one of my favorite gadgets to have around for those times you need something a little different.”

I will usually have the flash hanging off a long boom and triggered with Gadget Infinity Flash Triggers. In the studio I will also shoot tethered using DSLR Remote Pro.

As you can see, a subtle color on background can make a huge difference on a portrait shoot. Let’s take a look at several product shot images taken with and without the FX system in place.

Results
The results are exactly what I was looking for. The color is vibrant with a predictable fall-off allowing for easy adjustments so that you can get the exact effect you are looking for and for less than $40, it will work with virtually any flash brand.
