The most I’ve tried has been 400 Ilford. but the majority I use is 100. I would like to see more of your work with zonplates.

I’ve converted an old rangefinder camera to a pinhole and have been trying to figure out a film/ developer combination to get an EI of 25,000 ASA. Then I can use it as a point and shoot. Tried Rodinal 1 to 50 for 51 minutes stand development but I think I’m about 2 stops short (this was with tri-x). They are probably printable but losing too much detail in the shadows so I’ll be interested to see what you come up with. I also tried a 1 to 100 mix (Rodinal) and let it sit for 12 hours but there wasn’t any difference so I think I’ve hit a wall as far as the Tri-x /Rodinal combination is concerned. Interestingly I did the same thing with Tmax 3200 but it didn’t push any further than the Tri-x.

Other recommended developers are Xtol and Microphen but I haven’t got that far yet.

Nice to read your research on Diafine. My favorite developer! – but its no good for this project.
