I apologise if this sounds a bit long-winded but here goes:
Having completed a full calibration print run (Ilford Multgrade paper, Dektol) I find that while zones 1 through V are rendering acceptably, zones V11 and V111 are printing about one zone too dark, with some textural detail even visible in zone 1X. I originally used ilfosol 3 for the Ilford FP4 120/asa 125 film in a manufacturer recommended working solution of 1:9.
I understand one alternative is to develop a second roll film in D-76, using a dilution from the manufacturer's recommended working solution, of 1:3 for a development time of about 12 minutes. This should effectively lighten these zones by one zone each in printing, without discernably affecting zones 1 through V. Can some experienced individual out there confirm that this course of action is a sensible one to take or recommend some alternative, please.
