I just figured out that I had been over developing my film. I have been rating FP4+ at 64 but using the normal times for 125. No wonder my N+1 negatives have been so contrasty and off.
I am having trouble finding a reliable time. The massive development chart recommends 21 mins. which is more than the 125 time. This is not what I would expect.
So, does anyone have a good starting time for FP4+ at 64 in Rodinal 1:50.
