I accidently shot some HP5 at ISO 64, thinking it was another film. Anyone have any tips on pulling this 2.5 stops? There's nothing on the massive dev chart, atleast not with the chemicals I have on hand (Rodinal, Ilfosol, and the last of my D76). I understand pulling it is going to give me really low contrast negs. Should I just live with it, or might it be an idea to develop in a diluted solution to get out some shadow detail, then switch to a higher concentration mid way?
