Alright, second attempt. This time i shot it at ISO25, per the "one stop per decade" rule of thumb which I should have started with in the first place. Results are much better. I also developed it in Rodinal 1+60 this time and reduced development with a minute down to 11 minutes. Agitated as normal, one inversion every 30s.
Pretty much every frame is now something at least, but I'd say that the exposure latitude is so small that if I didn't meter for the shadows, it could have benefited from a little bit more light..
Next gonna try to develop it a minute less, want to reduce the fogging. Been thinking of getting benzotriazole. Does anybody have any experience with it?
Here are some shots from today:
