I ran into something a little odd. I shoot in Adobe RGB raw. Then I import my raw files into Lightroom and do basic color correction and other adjustments. Finally I export as PSD files to do my final work in Photoshop. My lab wants files with sRGB profile so when I am finished, I convert the profile and save as a high quality JPG. Now here's the thing that is bothering me: If I export my files from Lightroom as sRGB I get no color loss. However, if I export as Adobe RGB and then convert to sRGB with Photoshop, I see a noticable difference in the color. Any idea what's going on here? Furthermore, I would love some opinions about advantages to using 16bit vs 8bit, Adobe RGB vs sRGB. Thanks!!!!!
