May be an obvious question, but do you develop at the Film's ISO or the ISO you shot with the IR filter? I thought it was at the film's ISO, as the Massive Dev Chart shows for Rollei IR400. But the same chart lists different times for Ilford SFX w/ or w/out a filter.
Does it simply vary from film to film? If it matters, I'm about to shoot on Superpan 200, and I've read the development needs to be very precise for it.
Thanks! |
