I just developed a few sheets of the Azo I had with very good results. For my ABC negs, exposure times were about 5 minutes, and then developed in Agfa Neutol WA. This is really exceptional paper because it looks as if I could walk into one of the prints. I also tried one of my negatives developed in Rodinal and my exposure times were around 1 minute..although the negative was slightly thin to begin with. I'm really pleased with this paper. Its 30 yrs old and prints better than any of my current papers. I should be placing an order from Michael in the near future.
