When have I not screwed up? Particularly egregiously though was a few weeks ago. I had just got a Paterson tank and reels, which I had never used before. I had been using Kodacraft aprons because they are very easy to load, and the metal reels never worked for me. I felt like I should learn a system I could replace if it broke. So, lights out in the darkroom, and I’m trying to load a roll of 120 onto the reel. The entrance tabs on the reel are small and hard to hit, it’s hot in the room, at least 90f, so I’m sweating and frustrated.
I finally get the film started, and pull it on about 3/4 of the way around the reel. When I start ratcheting the film on, it actually ratchets off the reel. I know this because I hear he film hit the floor, at which point I feel and there is no longer film on the reel. So, on my hands and knees I search in the dark for the film, and eventually find it.
So I start again, eventually get it started. This time I pull the film a full turn, and again the ratcheting pushes the film off, rather than pulling the film on. A third time and the same thing happens. At this point, I was ready to switch back to my simple kodacraft apron, but I needed the lights on to get the tank and parts. So I threw the film in the Paterson tank, put the lid on, turned the lights on, got all the kodacraft stuff out, turned the lights off, and had it loaded in 30 seconds.
If you have ever used a Paterson tanks, you probably see my mistake here. I’ve always used metal tanks (even with the Kodacraft aprons, I use a metal tank, because the Kodacraft tanks can’t be inverted. I didn’t realize that the Paterson tanks require the central tube to be installed to be light tight. There was, maybe one salvageable frame. The Paterson tank works fine for 35mm but every time I try 120, it pushes the film out instead of pulling it in.
