That Buffaloe site has every formula I've ever seen and a few I haven't. Anyhow, use Michael Smith's amidol formula is the default, as far as I'm concerned. I got nice neutral-tone results from the Fein Forumla also. Get the chemicals in bulk from Artcraft Chemicals.... Regarding the above comment about Neutol WA: I've used this and really have nothing to complain of. It's certainly easier to work with (just add water, y'know). There's something finer about the amidol, though, I'd still insist. I've gotten into a routine where I kind of work up "proofs" with the cheap and easy Neutol WA, then if I think I have a hot image, I pull out the expensive and harder to use amidol and work up the final "fine" (presumably!) print.... BTW, I think you have to selenium tone w/ Michael's formula, but it works very well. Thicker dilutions than recommended by Michael (the intent of which is to get a neutral tone) give a very nice slightly-purplish brown -- actually, one of the best browns I've seen selenium produce (like, as compared to what it does to other papers). -jb
