I've saved a number of posts from rec.photo.darkroom especially from Michael Gudzinowicz and when I've tidied them up I'll post it.I wonder how Michael is doing these days. I miss his posts. He was chased off by a person who was not very respectful of him.The upshot of the posts is that Agfa altered Rodinal in, I think, the 1960s. The amount of p-aminophenol was reduced and the pH was increased to compensate. p-aminophenol is not an expensive chemical, but sodium/potassium hydroxide is much cheaper! Reminiscences of Agfa Viradon having its only expensive ingredient removed also (selenium)!John-- Richard Knoppow Los Angeles, CA, USA dickburk@xxxxxxxxxxxxx= = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = = ====================================================================== To unsubscribe from this list, go to www.freelists.org and logon to your account (the same e-mail address and password you set-up when you subscribed,) and unsubscribe from there.
