I seem to have awakened some evil spirits when i decided to use this film. I have shot/ruined 3 rolls, two 35mm and 1 120 so far and thought a post was in order. I use pyrocat hd 1:100 for all my films, pre soak, then develop- typically 11 min with agitation every 2 minutes. This worked nicely for Delta 400 and 100, but holy moley, not 3200. I shot the last bit of 35mm at 1600 speed, developed for 16 minutes with presoak, agitation for 30 sec initially and then 15 sec of agitation every two minutes, and got VERY thin negatives. Something in the film that does not like pcat?? My chemistry is not very old, mixed it a month or so ago, and am using it without problems on the other two films.
