>>3734140The marks are definitely on the negatives also.
>>3734153>>3734155Ah yea ok. For some reason I thought that effects due to expiration would manifest throughout the whole image e.g. a shift in colours, instead of just in spots.
>>3734175That's what I would assume too. It also doesn't happen for every picture on a roll. Maybe about 50% of the time. Perhaps depending on aperture and shutter speed, but there are instances where for two consecutive pictures that had the same exposure settings, one will have the black bar and one will not.
>>3734182How would I be able to investigate this?
P.S. I miss natura
