I use the Germain and the thing I like about it most is that it pulls well without adverse effects. I'm not scientific with my photography so this is an observation but with setup it goes to -1 and -2 quite nicely. My gut feeling (untested) is that the shadows come up quickly with this developer. I will probably making some Edwal 12 this weekend because it is drab and ugly in Milwaukee and I have spare sheets to develop!!...Evan Clarke
