I've been searching the web (including newsgroup archives) for the past two days looking for tips on how to do this. I finally got ahold of an old Adobe tutorial, but unfortunately, the technique is for color photos and I couldn't figure out how to make it work for B&W.
Anyway, here's my problem:
I have an old (25 years) B&W photo which has blotchy yellow-brown stains on over half of the photo. The stains are irregular in intensity, so it's not as simple as repairing a color cast. Making the photo grayscale only serves to make the stains dark gray. I've tried looking at the different channels, but the stains exist on all of them (to a lesser extent on Red in RGB, but noticable nonetheless. CMYK and Lab don't seem to be much better - unless I'm missing something, which is entirely possible.) Is there some trick to removing these stains other than painstakingly rubberstamping?
Should I be fixing this in the scanning process? If so, how? (I can
get ahold of the original again if I need to.)
I've posted a copy of the photo to http://www.retouchpro.com/forums/att...s=&postid=1943 so that you can see what I have to work with.
I'm fairly new at this and as always have picked a tough project to start with. (Actually, I didn't pick it - someone requested that I do it - within a week.) Any suggestions would be greatly appreciated!
Thanks, Jeanie
