Yes, that is obvious from my tests. But bear in mind that I am looking for a specific solution with these tests, i.e. how to get enought contrast from low contrast films like BPF, JandC Classic, HP5+, and even 320TXP when used in low contrast lighting and intended for printing with alternative processes. You must have a developer with a lot of energy to get past the relatively low Gamma Infinity range of these films with standard strength developers. Even the regular 2:2:100 dilution of Pyrocat-HD, which is a very energetic developer by most standards, comes up a bit short with these films in these situations.

I think this is an important consideration because in my experience a very large part of ULF work is done for alterntive printing, with low contrast films in low contrast lighting.
