I don't think FP4 Plus has a usable shoulder; neither does HP5 Plus. Plus-X or Delta 400 would be a better choice. Verichrome Pan can also be very good. D-76 1+1 for Plus-X. If you want a shoulder, you have to go to very slow films like APX25 or other old films like Plus-X. Delta 400 and 3200 are exceptions, and some of us here put them in the "old films" category.(posted 8067 days ago)I don't find "compensating" formulae work as they are supposed to with films I tried on the market today. Pyrocatechin *might* work better because of its hardening effect. High definition formulae on the other hand seem to work pretty well for what they are supposed to do without compensating effect.
