I don't have Hutchings' "Book of Pyro." In it, does he mention how long PMK will keep on the shelf? I've got half a bottle of solution A (or is it solution B) left from a purchase of nearly two years ago. I developed some "new" Tri-X 5x7 in it last night, and it seemed fine, except for one scene that was taken in the woods. That scene was early morning, with slight fog. Long exposures of 13 seconds were required, due to reciprocity failure (indicated exposure to place a tree log on Zone V was 4 secs. I gave 13 based on experience with "old' Tri-X). In spite of the long exposure, I developed this neg for my normal 15 minutes at 72 degrees because of the flatness of the scene and because I use an old convertible Symmar, which renders everything a bit soft, anyway. Nevertheless, this neg looks flat (haven't printed it yet, maybe I'll prove myself wrong when I do). I've tried extending dev. times before with this old lens and PMK, but anything past 15 minutes doesn't add anything. It's as if it plays out after 15 minutes of tray processing. I've ruled out old PMK because my other neg looks great. Is it just the morning fog making everything look flat? It actually wasn't that foggy out. My lens wasn't fogged, either.
