A Few Facts
- Adobe RGB and sRGB are two differently-sized and -shaped color spaces. Think of sRGB like a 3-gallon bucket and Adobe RGB as a 4-gallon bucket; simply, Adobe RGB is larger and can hold more varied and different colors than sRGB.
- If you shoot in the Raw file format, it doesn't matter what color space you set the camera to use. This gets overridden by the Raw conversion software, just like white balance does.
- Adobe RGB will only be interpretted correctly by software that is color management-aware, such as Adobe Photoshop. If your image-editing or viewing software isn't color management-aware, shoot in sRGB so that colors are interpretted correctly.
- File size is unaffected by color space choice.
Really, this is the only information you need to base a color space/shooting decision on. The Raw format should be the first choice, but sometimes (sports, for example) shooting JPEG is a better option. So if you shoot JPEG and use color management-aware software, shoot in the Adobe RGB color space. If your software isn't color management-aware, shoot in sRGB.
