color - What's the difference between Adobe RGB and sRGB and which should I set in my camera?

In my Canon 60D, there's a setting between Adobe RGB and sRGB. What's the difference and what should I prefer when shooting to RAW ?

Answer

sRGB is the most common color-space used anywhere.

AdobeRGB is a wider color-space which can represent more colors but with less precision when looking at the colors which overlap sRGB.

Neither color-space really matters when shooting RAW.

The embedded thumbnail or preview within a RAW file may be affected by the choice of color-space though, so keeping sRGB selected is usually the most sensible thing to do.
