Hi, I've been using HC-110 dilution 'B' with Tri-X for years. Mostly shooting 6X7. 1-What is the effect of greater dilutions? 2-What difference will you see with intermittant vs. Jobo agitation? I read that Ansel Adams actually developed for 18 minutes with 15 secs agitation every 3-4 minutes or so! (for compensation effect?)(posted 8382 days ago)Any input appreciated. I do have a densitomter and run Zone 1 and Zone 8 tests to calibrate film/developer. Thanks, Howard
