I also am surprised that very little is discussed regarding color spaces other than when to use sRGB and when to not. I'm one of the many that just sticks with prophoto because it has a wide gamut. Are there others who choose Adobe RGB because it works for them better? When I used film I used Joseph Holmes Ekta Space. I now notice that on Joseph Holme's site he has seven different color spaces. Who uses these? Most of this is way above me, but I read I and try to pick up new bits and pieces.
