I've been trying to get an answer out of this same problem for months now and many threads on this issue seem to imply it's from recent updates from Adobe. So far I see Adobe has not answered anything on this. This is a terrible problem - how in the hell can a photographer work with this program if the colors are not consistent between PSD and Jpeg versions of the exact same image after processing?
Come on Adobe - fix this GD thing!
What version of Photoshop & Camera Raw?
I seem to remember a problem like this a year or two ago.
I tried to find the thread, but I'm not sure what to search for.
Anyway, I think I might have remembered the problem. I think it was a bug related to the Camera Raw setting "JPEG and TIFF Handling". I think that, if you switch these off in Camera Raw preferences, the JPEGs behave themselves in Bridge. As far as I know, this bug was fixed.
Wow I hope this is miracle I'm looking for.
Out of town till Monday. Can't wait to try it out.
