Robert and list, I can't wait to try it. Rick suggested very dilute HC110, I will try Rodinal 1:100 first, just because I have that. I was reading a very old copy of The Amateur Photographer's Handbook in which Sussman advocates the use of Kodak High Contrast Copy Film with H&W Control developer. The claims the author makes for this emulsion/developer combo sound a lot like Tech Pan. It makes me even more curious about experimenting to see if I can fnd a developer that will get more useful tones from this film. Does anybody remember anything about this combo or this developer? I don't know AA's water bath technique, I will have to do some more reading.
