Yes, sometimes it IS who you know

I had heard there was an easy way to organize images from multiple cameras but I had poked around trying to find it but I never really figured it out. Of course, the actual answer was far simpler than I had thought and had thus overlooked it several times. I was recently talking to my good friend Rick Miller who is a solution specialist for Adobe, and had mentioned I thought there should be an easier way to accomplish this. Rick, not wanting to be stumped by a Lightroom question helped me look for the answer and sure enough, there it was…sort of.

Metadata is your friend

This is going to be so simple you may wonder how come you didn’t accidentally run across it yourself. When you are in the Library module, make sure you are in Grid mode. At the top of the Grid you should see the Library Filter bar, if you don’t, just hit the \ key. Next, click on Metadata on the Library Filter bar. Right here you will see that the images are group by camera model. If the different cameras you are using are all separate models, then you are set, just select the Camera model to filter all of the images associated with that camera.

If you were using different cameras but they were the same camera model, fear not, we just have to go through one more small step. At the top right of any of the columns you see there is a small icon, click on that and add a new column, now click on the blank column title and select Camera Serial Number. Now you can filter by the individual camera.

Timing is Everything

Now that we know how to sort on the images, we now need to have a reference point so that we can adjust the time on what set of images to match the time on the rest of the images. Now if you haven’t done the shoot yet, the best thing to do is have everyone take a picture of something like their feet. Even if you are shooting alone, just take one shot with the first camera, then swap cameras and take a shot with the second camera, there is no need to try to do them at the same time.

If you are editing an existing shoot, you need to figure out the time difference. With multiple shooters there is almost always a shot from each camera at the beginning, if you didn’t pick up your second camera until the middle of the shoot, this can be a little more tricky. But play along and let’s see how to do it anyway.

Let’s say our sync shot was taken at 1pm, and the second camera is off by 20 minutes. All we have to do is filter by the second camera, go over to the Metadata block and select the edit icon next to Capture Time. At this point a dialog box will come up with several options for time adjustments.

The problem here isn’t that the functionality we want (to adjust by 20 minutes) isn’t here, the problem is the text for the option isn’t very clear. If you read the description at the top of the dialog box it actually tells you that it will adjust the time of the image that is displayed and all of the other images that are selected will be adjusted by the same amount of time. So if we are seeing the first image, and we set the time to 1pm, all of the rest of the images will be adjusted accordingly and all of the images from both cameras will now be in complete time sync.

Video Demo

In the following video, Kerry Garrison shows how to adjust the time of your images to all sync up together.

That Cheatin’ Histogram

Let’s look at what happens when we take a picture with our DSLRs. The exposure meter in the camera is using reflective light instead of incident light so a man’s tux will show a different meter reading than a bride’s dress even if the exposure for both of them was correct since the white dress will reflect more light than the tux, thus throwing the exposure meter out of whack. Secondly, when we press the shutter the camera creates a JPEG image with all of your picture settings and an S-Curve applied. Yes, this happens even if you are shooting in RAW mode since the display on the LCD is actually the JPEG image which is also the image the camera uses to calculate the histogram. I can’t count the times that my exposure meter was dead center, the preview looked great, and the histogram was good but when I brought up the RAW image in Lightroom, the image wasn’t quite exposed as well as I expected. Anyone who shoots a lot can attest to this issue. Yes, your LCD and histogram are usually accurate enough, but if you want to be accurate all the time then you need a reading from the point of few of the subject by measuring the actual amount of light hitting the subject and not the amount of light reflected by the subject.

What does a light meter tell you?

I asked a handful of photographers who had never used a light meter what they thought a light meter would tell them and surprisingly few actually knew even the basic functions of all light meters did with “Measure the light I guess” being the top answer. Even the most basic of light meters will allow you to set the ISO speed you want to use, then you set the shutter speed or aperture to what you want to use and the meter will give you the correct settings for a proper exposure. More fancy ones can also fire your flash equipment and some will even calculate the amount of flash versus ambient light.

Let’s say we have a nice bright sunny day and we set our ISO to 200, and our aperture to f/16, if we take a reading we will probably get something like 1/200th of a second as our shutter speed for a good exposure. With most digital light meters you can then make adjustments to the shutter or aperture and it will change the values on the screen to tell you what to change the other setting to.

If you aren’t familiar with the relationship between ISO, Shutter Speed, and Aperture, you should read the article we have about it (Link: The Exposure Triangle).

Testing the theory

Ok, I am sure many of you are skeptical that your camera, even a high end pro-series camera isn’t going to be dead-nuts accurate, but let’s take a few tests and see what our camera is telling us.

The following is a series of images of a product that has a black front and a light top, not something a camera’s meter is going to be good at so it will help illustrate the point well. Simply adjusting the camera’s settings to center the camera’s exposure meter at ISO 200, f/5.6 the camera gave us a setting of 1/400th shutter speed. Shooting the gray side of a WhiBal card it changed to 1/400th of a second, and shooting the gray/white/black side we got a setting of 1/640th of a second. By doing this test we can see that the camera’s exposure meter is going to change based on how reflective the subject is. In each image you can also see Photoshop’s histogram to see where the image’s exposure actually came in at.

Image 1 – ISO 200 f/5.6 1/400th – Slightly Underexposed (Based on WhiBal Gray)

Image 2 – ISO 200 f/5.6 1/640th – Underexposed (based on WhiBal White/Black/Gray)

Image 3 – ISO 200 f/5.6 1/200th – Showing good exposure (based on light meter)

Now some people may say that a perfect exposure should be centered in the histogram, however, digital sensors retain more detail in the highlights than they do in the shadows so you actually want your highlights to be fairly far to the right without going into the last little bit of the histogram which is exactly what we got with the final image.

But how does the meter know what the background is?

One of the most commonly asked questions is how does the meter know what the background of the subject is, since that should affect the exposure right? Well, let’s just try some experiments and see what we get. The following images were taken using the exposure settings provided by the light meter which were identical for both images, take a close look at the histogram for each image.

ISO 400 f/4.0 1/125th – Properly Exposed yet histogram says its underexposed

ISO 400 f/4.0 1/125th – Properly Exposed yet histogram says its overexposed

Of course the white paper is providing some bounce light that is providing more details around the edges and since I only metered for the center of center of the phone. So yes, the background can affect the exposure because you may not be metering for any reflected light, although this is typically only a problem with a situation like this. If I wanted to expose for the edges, then I could have metered at the edges. Does this mean the background affected the exposure? Yes, but only because the background in this situation actually is acting as a light source that is reflecting light into the edges around the product.

Will a light meter work properly in every situation?

So far we have looked at using a light meter for incident lighting, where this can break down is with highly reflective surfaces or in situation where the lighting is uneven, in this case a reflective meter is going to be more accurate. Most all light meters can do both types by adjusting or moving the light sensor dome. In reflective mode, the meter is going to act just like the meter on the camera.

Like anything else, a light meter is just another tool that is designed for a specific purpose. Used properly, it can dramatically improve your exposures and you camera setup time. The following image was taken in bright daylight with a large diffuser to the camera right and a large beauty dish flash to camera left. Combined with the ambient light, that is three different light values. With the light meter getting a reading taken at the subjects face, and the meter facing the camera, the settings provided were certainly dead on.

Ok, I want one, what do I do?

Light meters, especially used ones can be had for pretty reasonable prices. I see meters like the Sekonic L-358, which is a pretty nice meter with lots of functionality, often sell for $150-$200 on Craigslist. Cheaper models with less features, but still fully capable can be had for as little as $50-$60.

Overview

Front View

I often see posts in different forums from people trying  to figure out how to provide remote power for on-location shooting. I have seen everything from picnic coolers full of electronics to generators with expensive inverters strapped on.  For the cost of building one of these picnic cooler power packs and your time to buy all the parts and assemble it, you are just as well off to spend the $349 for the Explorer XT and have a professionally built package that you know is going to work well.

Features

Carrying Bag

The Explorer XT is rated at 350 watts of  continuous power and 1200watts peak power. For studio strobes this can handle up to 2400ws. The Explorer XT is designed as a portable power source for most flash and power pack units to be used on location, away from available power.

The Explorer XT is equipped with two (2) 12V, 7Ah sealed lead acid batteries, with an auto volt-charging feature which accepts 100-240V. It also has a 14V car battery charging where an internal circuit converts the 12V/14V source to a 24V. It also has an auxiliary battery port, allowing the user to connect another battery in case you need extended battery life. Battery power level indicators with beeper and charging indicators allow you to monitor power consumption and charging status.

The Explorer XT comes with a handy carrying bag to make hauling it around easier. The bag opens on both ends to allow access to all of the ports without removing it from the bag.

Specifications:

• Power Output: 350 watts (continuous)/ 1200watts (peak)
• Number of output sockets: 2
• Battery: Two (2) 12Vdc, 7AH SLA provision for external battery pack
• Charging Voltage Input: 100V-240V / 14Vdc (car battery charger)
• Charger: Built-in
• Weight: 8.5 kg (18 lbs)
• Dimensions: 14.5″ x 5.5″ x 7″
• Available Models: 115V/60Hz (North American, Japan) 230V/50 Hz (EU, Asia-Pacific, Middle East
  230V/60Hz (Philippines)

Setup

Rear View

What setup? You take it out of the shipping container and its ready to go.  The only thing you need to do is keep it charged up. According to the instructions, you should keep in plugged in even when not in use, this will keep the lead acid batteries in optimum condition as well as always being ready for use.  This was a concern of mine since a fan is running and even though the instructions say it will use a trickle charge, I wanted to know how much power draw it was really taking. Using a Kill-A-Watt to measure to power draw I found that while the system is charging (charge light is blinking) was 80 watts, wow, that would be pricey to have plugged in all the time. However, as soon as the system hit a full charge (charging light went solid) then the power draw dropped to only 6 watts, now that’s more like it as I have numerous electronics around the house that use more than 6 watts when in standby mode so keeping the Explorer XT plugged in all the time.

Usage

The Explorer XT is designed to be dead-simple to use. Just turn it on and plug in your devices and use them like normal.  The Explorer XT has two outlets on the front that output clean power from the Explorer XT’s internal pure sine wave inverter.  Having a top-notch pure sine wave inverter is important as it helps protect the devices that you have plugged into it. Besides just being a portable battery solution, it can also be used in between your equipment and a low-cost gas generator. At first that may not make sense, why would you need the Explorer XT if you have a generator? The issue is that low-end generators can’t handle the peak demands that studio strobe lights require and they don’t have pure sne wave inverters. By using both a generator and the Explorer XT the Explorer XT will handle the load of the strobes while the generator will work to keep the batteries charged up.

Results

The only way to really test out the Explorer XT was to hook up some strobed and start shooting. While the unit is rated for up to 2400ws, I don’t have anything near that power, nor do I need it in my home studio. I hooked up two PhotoBasics Strobelites (150ws each) and one PhotoBasics StrobeLite Plus (200ws) for a total of 500ws and started shooting away with all three lights on full power.  The Explorer XT has three charge level indicator lights, High, Mid, Low, at 225 shots the light flickered betweed Hi and Mid and finally went solid on Mid at 250 shots. The only difference from being plugged into the wall socket is that the recycle time dropped from four seconds to five seconds, and if I was shooting as fast as they could recycle would creep up to about six seconds. A short pause in the shooting and the recycle rate would speed up again. At 250 shots and only having drained about 1/3 of the battery charge I finally ended the test since I don’t like putting unneeded wear and tear on my lights or camera but it did show me that I can easily do most any typical shoot that I do and still have plenty of power left to also run other accessories like a blower or laptop.

I am very impressed by the performance considering the small size and relativly light weight of the unit.

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.

Adobe Photoshop Lightroom 2.0 Camera Calibration from Kerry Garrison on Vimeo.

Author: Kerry Garrison

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:

Photoshop CS4 Fluid Zoom and View Rotation from Kerry Garrison on Vimeo.

Content Aware Scaling in Photoshop CS4 from Kerry Garrison on Vimeo.

The Adjustments Panel

Working with adjustment layers has always been a serious tool for hardcore Photoshop geeks, now this has been made much simpler with a new adjustments panel. This can be used to easily adjust Curves, Levels, Hue/Saturation, Vibrance, and more. New On-Image controls allow you to adjust colors in the image without the guesswork of trying to match a complex color. The panel features a wide range of modifiable presets for each type of control and more than 20 preconfigured, customizable starting points are included.

New to the masks is the concept of Density and Feathering to control how much of the mask is used. This is a huge improvement from before where deciding you wanted more or less effect would require constant redrawing of the mask.

Improved Dodge, Burn, and Sponge Tools

If you are a big fan of the dodge, burn, and sponge tools, one of the big issues in the past is that they could sometimes affect the color underneath in odd ways. The new versions of these tools work in a much more natural way and help you to make the adjustments you want while retaining tonal quality.

Improved Image Aligning and Panorama tools

CS3 has some really good photo merge tools and panorama tools, but CS4 takes these tools to all new levels. The improved algorithms improve blending, vignetting, and geometric distortion which results in much better final images. The blending tool can take multiple images of the same shot using different focal points and combine them into a single image with a greater depth of field.

Content Aware Scaling

Ok, this is some wicked cool sh** right here. What happens when you want to scale an image that has people in it? The people can get severly distorted ruining the new image. With content aware scaling, you can size an image and retain the original sizes of key elements like people. Using this you could change a horizontal image to a vertical image and the people or key objects in it will look the same while scaling the remaining parts of the image in a very natural and usually undetectable way.  When you see this in action, you will simply be amazed at what it can do.

Fluid Canvas Rotation

If you use a Wacom tablet or just need to view the world a little differently, you can now easily rotate the canvas around to make it easier to work on a it. Rotating the canvas does not affect the rotation of the actual image, this is simply a tool to make it easier for you to work on images by being able to look at it from different angles.

Smooth Pan/Zom and Flick effects

Some people may think that the new smooth pan/zoom and “flick” effects are just for show, but as you begin to use them you will see how much nicer it is to smoothly zoom in and out of an image and be able to toss the image around as if “flicking” it with your finger. The built-in physics engine makes this new way of dealing with images much more natural.

Bridge

I have always hated Bridge, I’m not afraid to admit it, it was slow, real slow, painfully slow to start up and slow to use. Even on my new quad core system with a nice video card, I still didn’t like Bridge. But get ready you fellow Bridge haters, Bridge is one sweet tool now. Not only is Bridge faster, but it has been improved in a number of areas. There are several new views such as Carousel view which makes working with large numbers of images signifigantly faster. Bridge now also has a PDF-based contact-sheet creator and preview along with web gallery tools. Bridge has certainly grown up and is more integrated into the majority of the CS4 tools besides just Photoshop.

Camera Raw 5

Take the Develop module tools from Lightroom 2.0 and put them all into Camera Raw and you now have Camera Raw 5. And I do mean virtually all of the tools like port-crop vignetting, the gradient filter tool, and the local adjustment brush tool. Unfortunately, Lightroom Develop presets are not available in Camera Raw.

Smarter Smart Objects

Smart Objects were introduced with CS4 and made a huge impact on how you dealt with new objects. With CS4, Smart Objects can now accept perspective transformations.

64 Bit Support (Windows 64 ONLY)

As a HUGE shocker to long time Macintosh users, the advantage this year goes to 64 bit Windows systems. Apple changed a bunch of things without telling Adobe and thus Adobe had to pull 64 bit support out of the Macintosh version. Are Mac users going to have to switch to Vista 64? Not really, only the heaviest of users is going to see much of a performance difference according to sources at Adobe.

Live Preview for Clone Stamp and Healing Brushes

As cool as the cloning tool and healing brushes are, the results have always been somewhat black magic, you just never really knew what you werew going to get. The new versions of these tools provide a live preview for easier and more precise cloning and healing results.

If you are using the new adjustment tool in Lightroom 2.0, this is going to save you lots of time in getting your adjustments painted in properly. If you hit O (oh, not zero), while you are in the adjustment tool you can turn on the overlay and paint with it still turned on. Hit O again to turn it off. You can also use Shift-O to toggle the overlay colors. A second tip is to use the Alt key to “un-paint” an area. This video shows how these shortcuts work.

Before using this technique you will need to install the camera profiles that are available here:
