Forgive me if this has been answered already but I could not find it.
I mixed up Pyrocat HD from scratch.
I want to develop Ektascan B/RA for multipurpose use: Silver gelatin prints, Azo paper, cyanotypes and eventually Carbon prints. If I can get good scans, so much the better. Don't have a scanner yet.
Temperature control in my darkroom isn't very controlled---it is somewhat dependent on outside weather. But I may be able to correct that with Ilford's table of temp corrections for development times.
I rate the Ektascan at 100 film speed, and I believe I have the exposure right. Daylight balanced fluorescents and LEDs for light. 1 sec f16 to avoid reciprocity issues---though someone suggested using Tmax reciprocity similar to the option 1 Tmax in the iPhone reciprocity app.
Tray development. Continuously 30 sec, 5 sec every 30 sec water stop, alkaline fixer.
Last night it was 74F in the darkroom chemistry, tried 8 minutes. In 300 mL for 4x5's in a glass tray you can put a 5x7 in. They looked done at 5 minutes but I was so sick of thin negatives or having them turn out too thin in the fixer compared to unfixed I let them go to 8 minutes. By visual inspection I can't tell 2:2:100 from 1:1:100 when dry except by the notch code in the film holder (per Harlan's suggestion). They are a little grainier than I expected.
Suggestions? Procedures you use?
When I have time I will set up another test a busy still life and see what shorter times do. That should reduce grain, right?
Thanks, Fr. Mark
