Thank you for all of the replies! I know that the developer was not exhausted because yesterday my order of processing was: 35mm Tri-X 400 (I did this first to test the chemistry), 120 TMAX 100, 35mm HP5. Since the TMAX was processed in the middle, I don't see how that could be the issue. I, too always keep the chemistry in order of use and this time I actually mixed the developer in with my 68 degree water directly from the stock box before pouring it right into the tank - so I know I didn't fix first. On the first day I developed for 8 minutes and 45 seconds because the water was really cold - it was 64 degrees. On the second, the water was at 68 and I developed for 7 minutes. In both cases I fixed for around 5 minutes. I was using a chart specific to Clayton f60 developer, and it said that at 68 degrees, TMAX 100 120 film should be processed for 7 minutes. Is a pre-wash not recommended for TMAX 100? The instructions at the lab I was processing in recommend a pre-wash. I've never had an issue with it before. I did see a lot of purple dye come off and when I opened the tank after fixing, there was still a lot of dye coming off and it was still very pink. All three types of film were processed in separate tanks. I processed the TMAX 100 in a standard stainless steel developing tank.

Hi, I am having a mysterious and frustrating film isse. Yesterday I processed a roll of 120 TMAX 100 film, which was shot with my Hasselblad 500cm. I have been using the camera consistently for the past year or so and haven't had any issues. The roll was processed with Clayton f60 developer. It came out completely clear - there were no edge markings or numbers. That has never happened to me before. I thought maybe the pre-wash or developer had somehow gotten contaminated with fix, since I was working in a shared darkroom. Today I shot another roll of 120 TMAX 100 in the same camera, and processed it, as well as 3 35mm rolls, all with the same chemistry. Before processing, I washed out all of the containers and mixed new chemistry to ensure that it wasn't contaminated. All three 35mm rolls came out - 2 rolls of Ilford HP5 400 and one of Tri-X 400 - but again, the TMAX 100 120 film was completely clear, with no writing or numbers visible. Since the 35mm film came out with the same chemistry, it doesn't seem like a processing issue. I thought maybe an issue with the camera but the numbers have been advancing and I am able to take the back off and see the shutter opening. Also, if it was an issue with the camera rather than developing, I would think there would be writing and numbers visible. The only other difference in processing the different formats was I used a metal tank and reel for the 120 and plastic for the 35mm but I don't think that could be the issue. It wasn't a light leak because then it would be dark instead of clear and the chemistry went in properly. Does anyone know what the issue could be? Is it possible those two rolls were defective in some way? I purchased them both together. Thanks!!
