But in Tri X or Delta 400 it works great and at recommended times! In other situations just extending the times makes up for the lack of density. But the diachronic fog in some situation indicates to me developing in over extended developer and so I dilute less. I've run 2 liter tanks with 16 rolls of Tri x in them rolled back to back 2 to a reel. Those tanks get 19 minutes instead of 12. A thought of print throughable fog. But I've stopped doing that. The Xtol is worth it…doing more runs. But I've run an awful lot of film that way in many other developers. The Xtol is worth it. So I'm sticking to 1:3 in most situations 4 rolls of 220 Plus x in a 2 liter tank looked great at the recommended time. Mark Rabiner
