  Q. Ascorbic Acid based developer adjustments

Asked by David Doler    (K=467) on 3/27/2003 
I'm going to be developing some Fortepan 400 120 rolls I got cheap. I use Ilfosol-S exclusively, but there are no times listed for it. I've interpolated possible Ilfosol-S times on HP5+, Tri-X using known Ilfosol-S, ID-11 and D-75 as a start. I've got about a 20% greater time - like 13 minutes at 60/20 degrees. Anyone agree or am I going about this the wrong way ?

correction - I mean D-76 or course

I've done a couple of weird film/developer combos using your logic... They worked out ok and I've since fine tuned them on the occasion that I've used those combo's again. Ideally you'd do a test of course :)
