Colors are the smiles of nature.— Leigh Hunt

Space is to place as eternity is to time. —Joseph Joubert

These days, most DSLRs and mirrorless cameras offer Color Space options that are completely different from their Color Balance settings and are used to adjust the camera’s color balance settings to match the light you’re shooting under so that it appears natural or neutral—if that’s your intent.

 

How I made this photo: The above photo (of what I think is a classic “Midget Racer”) was made at the San Diego Automotive Museum using a Canon EOS 30D and EF-S10-22mm f/3.5-4.5 USM lens with an exposure of 1/15 sec at f/4.5 and ISO 400 with a plus one-third stop exposure compensation. The Color Space used was Adobe RGB; the Color Balance setting was Auto White Balance.

Space: The Final Frontier

The two Color Space options are typically available in a DSLR or mirrorless camera’s custom settings are Adobe RGB and sRGB, so it seems simple, just pick one. But here’s the problem in a nutshell:

sRGB (Standard RGB) was created in 1999 and its goal was producing color consistency between hardware devices. It defines a gamut* of colors that represents each color and can be used by monitors, scanners, printers, and digital cameras. sRGB has been incorporated into most Internet browsers to make sure the colors appearing on Web pages match the color scheme of the operating system. Because of the color consistency it creates, most hardware devices that work with images now have as the default setting. All of which sounds very inviting, doesn’t it.

Adobe RGB is designed for photographers whose work may appear in print (or in prints) and offers a broader range of colors than sRGB. If you want to really make yourself crazy, you can Google “sRGB vs. Adobe RGB” and read opinions about these differences from a wide range of viewpoints. Being a pragmatist, I suggest you shoot some tests, make some prints, look at some images on the web, especially your own website, and then make up your mind. This is the kind of testing methodology that photographers used to do in the film days and it’s still valid today, even if the tools are a lot different.

*What’s a Gamut? In color reproduction, gamut represents a subset of colors that can be accurately represented under specific conditions, such as within a given color space or for a certain output device. Converting a digitized image to a different color space can typically alter its gamut, i.e, some of the colors in the original will be lost in the process.
