Is it the case that certain ingredients of film developers, e.g. glycin, pyrocatechin, etc. can strengthen film emulsions so that they become more scratch resistant during the fixing and washing process? I have used two developers on Efke PL 100 (well known for its fragility) and have experienced scratches with one but not with the other. Respectively, Pyrocat HD and PF TFX-2.
