Mamiya RZ: Cause of Vertical light Streak on Negative?

Discussion in 'Medium Format' started by andre_noble|5, Dec 9, 2012.

  1. Hello,

    I noticed on two separate rolls of BW film, developed on different days and different developer - different lenses to), closer to the left edge
    of the negative, there is an appx 8mm wide vertical strip along the developed negative that appears lighter. It only on one frame for each
    roll. Its not exactly in the same location on each frame either. Two different emulsions.

    I am not certain if if involves the same body or same back.

    If it were a light leak, I would be a dark strip. but the strip is light. In both cases perfectly vertical and constant width.

    What could cause this?

    I processed one of the rolls at home, The other at a local pro lab.

    Thanks for any suggetions.
     
  2. The location could be chalked up to the back orientation, a scan might help bit I'm inclined to say it's something with the baffles on the mirror at this point.
     
  3. One of the problem images the film
    back was vertical, in the other problem
    negative the film back was horizontal.
