APX-25 streaks easily on drying; a good approach is to leave it in the foto-flo for several minutes. If you use a film drier, do not use the high setting (that is probably what happened with the lab).(posted 9411 days ago)My lens resolution tests with the 120 version showed that APX-400 had lower resolution than other 400 speed films; an old Modern Photography article comparing it to Tri-X found the same in 35mm. APX-25 on the other hand is sharper than anything except Tech-pan, and IMHO has a more attractive look.
