Color system, also known as color space, refers to the manner in which colors are abstractly represented as numbers. In simple terms, the color space determines the colors that will be visible in a given photograph. When buying a camera or photography software, you can select one of three different types of color systems, each of which have unique properties to suit specific needs.
The three options for color systems include sRGB, Adobe RGB and ColorMatch RGB. The sRGB color space is a widespread system that is the default setting for Windows XP, web browsers and most image editors. As such, sRGB is the color system used by nearly all digital cameras today. If your digital camera doesn’t come with color space options, it is likely to be equipped with sRGB.
The ColorMatch RGB is a middle of the road color space that includes more colors than sRGB. While it is not usually available on point-and-shoot or digital cameras, the ColorMatch RGB is a color system that easily brightens photos, especially those that are too dark.
Finally, the Adobe RGB is a colors system that is more extensive than the sRGB in that it offers a broader range of colors. Consequently, this color space is generally only available on higher end, more expensive cameras.
The Adobe RGB color system is also compatible with CMYK links. Because it houses a broader color spectrum, the Adobe RGB is the best color space option for printed photos.
