On page 96 of the Canon T2i manual it recommends leaving the colour space setting on sRGB, which I did. But, in a course I'm taking right now the teacher went through all our camera settings and wants us to change the colour space to Adobe RGB, which I have done. In retrospect I really should have gotten a second opinion before making that change. So I'm hoping some of the more experienced Canon shooters can help me out here. The manual claims that in Adobe RGB images will look more subdued on a sRGB personal computer environment and with printers not compatible with Design Rule for Camera File System 2.0. Post processing will therefore be required. I don't print my photos at home, I send them out.
