It's freezing in my darkroom, but I want to make some 11x14 contact prints, so I'm having another go at B&W printing using a Jobo Drum. Normally I use trays, which is easy. I'd tried with some 5x7 prints a couple years ago, and didn't have much luck then either. In doing some research it sounds like the problem might be having water drip from the drum onto the print, before developer gets to it. Can anyone confirm/explain this, and does anyone have a working process for doing this?
