The big issue is that after I save my work as the final jpeg, when I open it using the default Windows 7, the blacks are way too intense as well more saturation in the colors. I lose a lot of detail in the shadows. But when I reopen that same jpeg back in to Photoshop, it goes back to the original version I saw as I edited it.
To make things even more frustrating, in an effort to explain my problem to some friends, I thought it would help to create screen shots of the two versions I'm seeing. I took a screen shot of my photo opened in photoshop and I pasted it into MS Paint. It still looked like how it looked in Photoshop. But when I saved it as a jpeg and opened it in Windows Photo Viewer, my photo in the screenshot no longer looked like it did in Photoshop, or as it looked in the screen shot pasted in MS Paint.
I have tried many different things and I can't figure this out and I can't understand why I never had this problem before.
Here is a screen shot of my Photoshop color settings.
I had a color problem a while back that was fixed when I changed from convert to working RGB to preserve embedded profiles. I haven't changed anything since, so I can't figure out why all of a sudden I am having this problem.
