In my black and white film development journey I've tried many aspects of the art.
Starting out with D-76 and Kodak Tri-X 400, I found that I really didn't like mixing the powdered developer and fixer. It was time consuming, the finer dust would escape from the beaker and sometimes the chemicals wouldn't mix very well. I also found the rather short development times to be less forgiving of timing mistakes.
Eventually, I ended up at the opposite end of the spectrum: stand development using Rodinal.
I was intrigued by stand development because it seemed to fit my loose development practices. All I had to do was agitate for a bit then let it be for an hour. Easy!
All was well except I was noticing that my results were all over the place. Some rolls had uneven development around the sprocket holes, the film tended to fog up very badly and highlights seemed to blow out very easily.
After much experimentation I ended up settling on a method somewhere in the middle, gaining the looser tolerances of stand development, but the consistency of normal development.
I still use Rodinal as the developer mainly because I like the sharpness it brings to the photos and the long shelf life since I don't regularly shoot with black and white film. The difference is that I am dramatically shortening the stand development (more appropriately semi-stand development) time into the normal development range of about 18 minutes at 20°C. The initial agitations are similar to a normal development process, but taper off to a semi-stand-like development process to let the shadow details come out.
The combination of the 1+100 Rodinal Development with Neopan 100 Acros film is a good match for my style. I love the rich blacks and the even tempered highlights. There is also a lot of detail in the mid tones without looking like a grey mush.
The only complaint that I have is that I'm finding ISO 100 film to be too limiting for medium format. So I'll continue the search for a pleasing medium speed combo, but in the meantime I'll definitely keep working with this beautiful combination!
