This is my first post here. I would like to develop some Fuji Acros 120 film in Ilford HC developer (which has the same times as Kodak HC-110). However, looking at the Massive Dev Chart, the starting point for development times at EI 80 is 4.5 minutes at 1:31 dilution, which seems rather short. I have read that it is possible to increase the dilution of this developer to 1:63, but I am unsure about where to start with development times with this new dilution. Any tips? Thanks.
