You will have to experiment to find the correct ISO/ASA rating and developing time. TriX is ASA/ISO 320 in sheet film. Processing is 6.5 to 7 minutes at 68°F in HC110 dilution B. From experence 65°F reduces base fog from non usable at 68°F to usable. I don't/won't use Rodinal. I woud start at ISO/ASA 12 and process for 18 minutes at 65°F in HC110 dilution B, fix normal, then evaluate when dry. |
