    During the recent RFF Euromeet in Berlin, I accidently exposed a roll of Pan F+ at EI 125 instead of EI 50. Now that I'm home, I'd like to try to develop it but I can't find any data.

    I know that Pan F+ is a contrasty film to begin with and I assume it'll get worse with push processing but I would still like to give it a try. I got D76 and Rodinal at home, PMK and Perceptol in the photoclub darkroom (but none of them are very good for pushing, right?). My first guess, based on extrapolated data from the MDC, is approx. 15min in Rodinal 1+50. How does that sound?

    With X-tol 1:2 I have established a film speed of EI25 for PanF+, I'm sorry I don't have my deveopment time handy. So from my experience I would think of EI125 as about 2 stops underexposed.

    Rather than going with Rodinal 1+50 I would be looking at Microphen or at stand development or some other highly compensating method. I'm not sure of the applicability of a two bath developer in this situation as it may not help shadow detail enough but I'm sure others will chime in soon.

    I would give it about 25% more than your usual time with your usual developer.
