Sometimes I like to experiment. Saturday I wanted to test a russian rangefinder (please do not laugh) I had just cleaned/tuned and, at evening, went to a nightime flea market near Rome. I took a roll of HP5 and pushed it at 1600.
Sunday I discovered that I had only some ilfosol left in my cupboard, but even knowing it is not exactly the best for pushed film, I proceded anyway. Yesterday it was so hot in Rome that tap water came out at 30 Celsius and I decided to push the developing temperature to 24 C instead of my usual 20.
The developed film seems to have a bigger grain and the grey tones have a better balance than what I was expecting.
Does the developing temperature has influence on grain and tones rendition? hat are your experience?
