Debra,(posted 9094 days ago)Stay with Rodinal. After experimenting with many rolls of Pan F+, I have been able to control the highlights with dilutions of 1+ 50 and 1+ 75 at 68 deg. for 5.5 minutes and no agitation. The developer against the highlights becomes exhausted while the other area continue to develop. The tonal range is excellent.
I decided to try this "stand" development from using FX-2 developer according to the instructions for 55 minutes! It produces very good results. So I then tried a stand development using Kodak X-tol with Pan-F+. It produced beautiful negatives also. I compared enlargegements of a controlled subject and decided that in a close competition, Rodinal won in sharpness, tonal range, and shadow and highlight detail. I can't say enough about Rodinal for slow film. I wish that Ilford made Pan-F+ in 4x5 so I could use this great combination. For that I use PMK to control the highlights. It's an even more amazing developer. But it's not as simple to use.
Good Luck.
