I read somewhere that Adobe RGB is better, but the truth of the matter is I can't see any difference.


Open an image in Photoshop>Edit>Convert Profile (choose the other profile). Convert it, then open History palette, click back and forth on the processes in there. I don't think you will see it change. So If you use a printer that prefers on or the other use that one to make them happy.


Make sure Photoshops Default color space is the same so you get predictable output. Never let it change color profiles when opening. You want to be able to watch it happen to see if colors shift.
