I used to work at an archive that housed all the original master prints of Adams and W.Eugene Smith. I held them in my hands on a daily basis and it was a good way to learn. Smith was teaching there in Arizona, at the end of his life, so we had the opportunity of not only studying all the original work but also asking him about it and often recording his conversations for posterity. It is a strange thing but Smith shot on the run and in chaotic situations and often with a not very powerful flash unit in very dark situations with a Nikon. More often than not his exposures were far from ideal. He used Potassium Ferrocynide bleach on so many of his world famous prints that it would blow your mind. The famous one of Albert Switzier close up or the burial group from the Spanish Village series for instance. He used the bleach right on the surface of the print to lighten subtle info in the shadows. It's strange but it worked extremely well. These master prints were of course first used for reproduction in Life Magazine but for print sales he either repeated the process or had 4x5 copy negs made of the "master" prints. I did some of this bleaching back then out of curiosity. The one thing that is extremely important is that you treat the film or prints with a strong hypo clear solution and wash the material for a long time! If there is even a slight hint of the bleach left on the print or film it will turn a sick yellow orange color in time. I've seen a lot of those stained prints around. We actually had a guy in graduate school who did some really beautiful creatively bleached prints, a whole body of work, and they all stained before he graduated. So be careful.
