Just got this roll developed, the first from a new camera, and I noticed that four pictures have this straight thin white line running through it. Looking at the negatives, I can see the line going through the film, running through the border between pictures. But its only there on about 4 pictures in the middle of the roll. Is it possible to tell what caused this? Or should I just shoot another roll and take it somewhere else.
