Strange scratches on negatives
I went to my local lab to pick up a test roll of Kodak HD 200 from my newly refreshed Yashica Electro 35 GSN. I didn't get any prints made because the images weren't worth it, mostly just running through the gears to see what came out. When I looked at the negatives, I began seeing very faint scratching in non uniform directions, not like from processing or winding. These were faint, and in all directions, on the base layer not the emulsion side.
The lab/studio owner (40+ years in the business) was a bit perplexed as well. She kept the negatives to consult with some friends of hers about what they think it could be. Again, I don't see it being from transiting film as they don't run length wise. Also I currently don't have a pic or scan as she has the film. Any toughts? Has ayone run into this before?
