Scratches Through Negatives


For about six months I have been getting negs back with long scratches through them. I changes cameras and I changed labs. Think it could be the film? All bought at different times at B & H - Portra Films. I am beside myself. Ditched two cameras because of it. Thought I had ruined the insides with dirt. This new Canon EOS 3 has not been around any dirt. I have hundreds of dollars of these films. Can someone help?

  If you are getting the same scratches with different cameras AND different labs, it could be the film canister. Could be that the film canister is putting scratches on the film. So if you haven't tried a different film brand, that might stop it.
One other reason that is kinda rare but can happen is that static can cause fine light streaks that look like scratches. Static and visible light are both electromagnetic energy. And static can cause streaks. Mostly found in cameras that have a fast rewind, or if somebody hand rewinds the film fast. It makes a static charge build up, just like dragging your feet across the carpet. And since we're in the winter months, where you always get a shock when you touch a doornob, that could be it.
But go to the store, and buy a 12 shot roll of film and see what happens. And also the EOS3 may have a slow rewind option, so you can try that also.

Jayne M. Silberman   Different labs and different cameras. How could the cannister do damage? Started about 6 months ago when there was no weather related static. Hair thin scratches that are perfectly straight. I keep everything refrigerated could that be it? I let warm up before load in the camera.

Will buy a roll and see what happens. Will also take two refrigerated rolls to the lab that have not been exposed just to be processed... they will expose there and then develop. I will decrease the wind speed on my EOS.

Jayne M. Silberman   Thanks Gregg. You were right on... I slowed down the rewind and bingo! That did the trick.
