I'm trying out my new 4x10 for my 45H-1 and has come across some artifacts on my negatives that I can't explain
There are areas of light exposure that goes parallel to the long side of the film holder perhaps 5 mm in from the border.
Camera is Chamonix 45-H1 with 4x10 back and chamonix film holder and Fujinon 125mm SW
Of each subject I did two exposures and the artifacts are identical of both. To me this rules out light leaks in the holder or when loading and unloading film or holder.
The two exposures were also were developed separately, ruling out the development process as the culprit.
Film is cut up 8x10 Fomapan 100
So it has to be something happening in the camera I guess. Bellow, internal reflections.
Thing is that two other subjects from the same day was unaffected.
Anyone seen anything like it or has som idea or suggestion?
