I am trying to get together a game plan for testing of oddball films I could not resist acquiring (aerial, xray, microfilm and graphic arts). Kind of like FAS instead of GAS.
I have some low gamma developers identified to control contrast.
Where I am confused is what step to do first when I don't yet know a film ISO or a development time in a given developer.
I think if I knew the development time I could expose Zone I and V or VIII and an unexposed strip and figure out a film ISO.
Do I do something like determine the time for base + fog to get the processing time first?
I'm not worried about printing yet...just the film.
I have an XRite 301 transmission densitometer.
Thank you
