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.

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.

Does scaling images have to suck?

The problem with scaling images up is that the software has to examine the image and guess what pixels need to be added to make the image look right and maintain quality, detail, and sharpness. Without a very sophisticated algorithm, you end up with blocky and blurry images when you are done. This is exactly what Genuine Fractals was designed to solve.

Photoshop CS4 vs Genuine Fractals 6

While Photoshop does an ok job at upsizing images, it most certainly does not do a terrific job. Let’s take a look at what Photoshop can do versus what Genuine Fractals can do on a small photo.  The original photo we are going to use is this photo that originally was at 640px wide. Let’s pit Photoshop CS4 vs. Genuine Fractals 6.

The following examples show the difference between the two programs:

Scaled with Photoshop

Scaled with Genuine Fractals

As you can see, the image scaled with Photoshop is much softer, looking out of focus than the one scaled with Genuine Fractals. This is a rather extreme example since we started with a pretty small image to scale up but it does prove the point. My normal use is for scaling screenshots up from 72dpi to 150dpi for use in the books I am writing and it does an awesome job of that.

Using Genuine Fractals

Genuine Fractals is a Photoshop plugin and when activated opens in its own interface with the toolbar on the right Besides just scaling images up or down, it can also add texturing and film grain which can help improve the perception of sharpness.

Another useful feature is a tool to create the data needed for gallery wrap images where the image continues off the edge of the frame and continues along the outside edge.

Key Features of Genuine Fractals 6

Genuine Fractals may seem like a pretty basic program but it does have an impressive list of features as well.

• Resize images up to 1000%
• Maintain sharp edges and minute detail
• Control texture for maximum quality with different image types
• Apply sharpening based on luminosity only
• Add simulated film grain for perceptual sharpening
• Includes document size presets for common photo and paper sizes
• Supports cropping and resizing in one step
• Supports resizing RGB images
• Supports resizing grayscale images
• Supports LAB images
• Supports layered Photoshop files
• Tiling feature – create tiled mosaics
• Batch process multiple files at once
• Supports resizing CMYK images  **
• Gallery Wrap feature – add extended margins for printing on canvas **
• Integrates with Photoshop Lightroom **
• Integrates with Apple Aperture **

** Only availale in the Professional Edition

System Requirements

Certainly some people think that David has lost his marbles, but is he completely off-base here? Even Chase Jarvis has some thoughts on this idea. I do not believe this idea is anything really new here, and perhaps explaining it in the way David does may make it sound like something new and unique. The fact is, many of us have done free work for a variety of different reasons. Here are some examples of what I have done, and often continue to do with any money exchanging hands.

Work with models when I need subjects for lighting tutorials or to experiment with new products
Absolutely, I don’t get paid for writing articles for CameraDojo (any potential sponsors, please contact me) so when I need subjects for shoots to try out new lights, techniques, or for a subject of an article, I turn to craigslist or Model Mayhem to find someone that will work with me in exchange for some nice headshots, body shots, or whatever they need for their portfolio. Since I am not bound by any constraints during these shoots, some of my best work has come out of some of these collaborations.

Shooting with big names in the industry
My bread and butter is wedding photography and I have had the pleasure of shooting with a number of excellent photographers which is how I learned the ins and outs of the business. I did plenty of those shoots for free in order to learn that segment of the trade. I would still be willing to second for the likes of David Ziser, Dane Sanders, Mike Colon, Frank Salas, or a number of people who are vastly more successful than me in order to get the experience working with them.

Social Interaction with other like-minded people
Two weeks ago I got together with a number of other photographers up at Robert Evans’ studio in North Hollywood to do a trash the dress shoot for a couple. They probably ended up with hundreds of images from a dozen photographers, none of which charged a nickle. Robert opened his studio, I brought fog machines and dry ice, Candice supplied several dresses, and a dozen people worked together on a project that was for the betterment of all involved. This was so fun and worthwhile, we have decided to try to do it once a month.

I suggest you take a good read at David’s article as well as Chase’s response and think about what you are doing with your photography. This will actually tie in well with next week’s podcast with Dane Sanders about figuring out who you are as a photographer. In these tough times, we need ideas that are outside the box, those who survive and push through, those who do whatever it takes to weather the storm and find ways of improving themselves at the same time will flourish as things get better.
