First, a little about my workflow: I shoot in RAW and do initial adjustments in ACR before making any final processing in Photoshop. I have read conflicting reports concerning the use of Adobe RGB color space, and would like to know your thoughts. SIDE 1: Says if you always use Adobe products (such as ACR and Photoshop) then switch your color space mode in-camera to Adobe RGB. There is a wider color spectrum, yadda yadda yadda, etc. SIDE 2: Never use Adobe RGB if you plan to make prints. Many printers do not recognize the Adobe RGB color space, and the end result could be flat colors.
