Well, if you save it, then run the conversion, you usually have to save it again. Example: I save my PSD file then export to bright, and it asks me to pick a file name and saves it again. If you're just testing, you can go to Image > Mode > Indexed and choose "Adaptive" from the type box and "8 bit" from the second drop box. Doesn't always look the best, but if you're still working on the skin give it a shot.
Having said that, sometimes it looks better than bright, sometimes bright looks better than it.
Straffo, are there any other conversion tools out there, like bright? I'd be interested in comparing some of them.
