Thanks. I now know what happened. I intended at first to use a Paterson tank but the second roll stuck (ball bearing) so I had to switch to my SS tank. In the meantime i put the loaded roll inside the Paterson with the lid on but whithout the center column. Stupid me. So light leaked in through the lid as I turned on the light to find the SS tank (sounds like something from a WWII movie).
Ok. Mystery solved. Culprit found. As per normal, I'm an idiot. Silver lining is that nobody paid me for these pictures and the camera is OK.
Whenever I do something silly in the darkroom, I say something like this out loud, but with the addition of enough profanity to make someone outside my darkroom think I was reciting a scene from The King's Speech (if you havent seen the movie, go see it and you'll know what i'm talking about )
I usually sing a song I have developed for these kind of purposes, the lyrics go like this (translated to English):
"I am stupid, I am stupid, I am stupid, I am stupid" and so on!
Back when the earth first cooled I was maybe 13 and new to film developing. I had mixed up developer and fixer, and foolishly hadn't labeled either, since the fixer had that fine dill-pickle odor. I load the tank, an old Kokak apron job (anyone remember them?), pour in the developer, and note through my cold-impairednose that dill-pickle odor! Yep, cleared that film in seconds! Believe that I labeled stuff after that!
