[QUOTE=photomc] also - does semi-stand development work well with roll film

In my experience, it does. In the thread "FP4+ grain in Rodinal" of a few weeks ago, I mentioned that I had successfully developed an out of date film in several years old developer. I did not give it 30 minutes, more like 20 but the whole thing was an experiment and, although there was nothing on the film that was of major importance, the whole film was good and each shot was a bonus. Shoot off a spare film and try it.
