Hi,
Is it possible to develop these two films together in the same Paterson tank (using a Mod54)?
From the Massive Dev Chart:
HP5+ in Ilfotec DD-X
1+4 400 9 20C
Delta 100 Pro in Ilfotec DD-X
1+4 100 12 20C
The D100 was shot at box speed. I have two sheets of HP5+: one shot at 8 secs (according to light meter reading) and the other shot at 22 secs (taking into account reciprocity failure).
Maybe develop for 12 minutes, developing the underexposed (8 secs) HP5+ sheet, and not the correctly exposed (22 secs) sheet?
I could wait till I've shot more sheets of each film, so just load up the tank each time with one type of film, but I wanted to develop what I have sooner before returning to a site.
