will this article include your suggested times for different films? people are always asking about times for different films and if there was one main source you could point them to it might help with a lot of confusion. I've been looking through a number of archives across the net for suggested times for HP5 (which include a range of SBR's, not just the "normal") and have found a geat deal of information but have trouble separating them into times for azo, pt/pd, or enlargement on silver, which dilution they are at, and the film speed to shoot at. I know I need to be doing my own testing, but I haven't even been able to get into the darkroom since my last postcard (quite a while ago).
note: Francesco's question is definitely one that needed to be asked directly as it concerned more extreme SBR's than usually used.
