I have been experiencing light leaks with my 4x5 film off and on for about a year. The most aggravating and non-comprehensible problem is after development, when certain negatives will have very obvious solid stripes of exposure (or lack of) running though them. The stipes (usually only one stripe) are parallel to the borders and are consistent in their over or under exposure. They are usually at least one inch wide. When printing, I cannot seem to burn or dodge away this problem. I have tested all my film holders, so the only other variables are-
-the film box I used to store shot film while traveling
-my changing bag
-my camera, but I doubt it
It has only happened with a couple of negatives, which makes diagnosis very hard.
If anyone has run into this problem, please let me know. Also, is film below 800 speed susceptible to X-ray damage in airports? Is paper OK to put through an X-ray machine?
Thanks-Jon
