Need some advice! Im noticing a thin black line down the center of some of my 35mm b&w negatives. It first appeared last time I was processing on some Ilford Delta 3200. The line was across nearly all the frames and spans between the frames too. After talking to some people, we concluded that it was a fluke, maybe even a manufacturing defect in the film. However, today Im processing again and the anomaly appeared on two rolls of 400 Tri-X and several rolls of Ilford Delta again. in some cases, it only last for several frames, in others it goes over nearly the whole roll. Okay, now please, I am not interested in lectures about plastic vs. steel reels. Ive done the research, had the experience with both and use plastic. In particular, I use the following Dot Line reels with very large loading tabs on them. adorama/DKTPU.html#reviews I noticed that when using these, they created a similar line down the first several frames of the end of the film that was on the outer-most spiral of the reel. I think this was due to chemical surge between the two tabs. My solution was to wind the film on the reel backwards so that the leader was loaded into the outer-most spiral of the reel. Because the line only seemed to occur in this area of the film and this area of the film was now blank, the line was not affecting my photos. Im wondering now if this is the same line or could be caused by something else. Ive tried both the spinning and shaking methods of agitation but both have resulted in lines. The only other commonality I can think of is the camera itself. I am not 100% sure which of my Nikon bodies was used for each roll but so far, the issue has only occurred on rolls that I THINK were taken with an F2sb. Could the camera somehow have a light leak that only forms a line down the center of the film? Maybe where the head attaches or something? Any thoughts would be GREATLY appreciated!
