After a slight hiatus from my darkroom, due to a particularly nasty stomach virus, I downloaded film from my drying rack... cutting and placing it in negative preserver sheets. Nothing out of the ordinary here, until... The last roll of 35mm (36 exp.) was completely solid density .. and I mean about 10.0 +. Solid, no indication of frame numbering or any sort of space where there would normally be base fog. I am at a loss to explain this -- it would have to be a MAJOR "light strike" - one I don't think I would have missed - or - 1. Processing color film in black and white chemistry (Rodinal 1:50). 2. Processing black and white film in color chemistry (C41). 3. Plain old pouring the wrong stuff into the tank... 4. Curses from long dead brittle Puritans who work to prevent nudes from being brought into existence ... 5. "Nov smoz ka pop!" - something else I am missing - totally. Your thoughts, guys...? What would cause total black - everywhere?
