Hi,
I just bought a Chamonix 8x10 and processed my first sheets from it and I'm getting stripes on the long edge of my negative, parallel to and mimicking the form of the groove that holds the film in the holder. I suspect this is some kind of reflection going on because the film holder is too shiny or its not sitting tightly enough in the back of the camera.
See the attached picture for an example of what I'm talking about. I'm attaching the whole picture and a detail of the corner that shows these stripes. I was using a plastic Fidelity film holder.
I'm certain this is not a processing issue because in the same batch I processed film from another camera (a Wehman 8x10) and the negatives do not exhibit this problem.
Can anyone advise on how to modify either the camera or the film holders so as to eliminate this problem?
Thanks!
