One of the most common questions asked by photographers is, “Which working space profile should I choose when converting RAW files, when scanning, or when setting up my digital camera?” Working space profiles (or editing space profiles) are generally embedded inside files, such as TIFFs, PSDs, and JPEGs. If you shoot in RAW mode, the working space profile setting (usually sRGB or Adobe RGB [1998]) that you can often choose in your digital camera, has no real meaning until you export your file and choose a working space profile using RAW processing software.
When you scan film or a print, you will also have different working space profiles from which to choose. To capture a very wide range of colors, I recommend choosing ProPhoto RGB or Adobe RGB (1998). However, many users will choose sRGB, which can produce very good results.
