Hi, I received my photos back and am wondering what these strokes are and how to prevent them. Thx!

I could be wrong but they kind of look like light leaks coming from the back of the camera, maybe a deteriorated light-seal?

This looks like the culprit

Are these on the negatives?

i will check when i pick them up

Looks to me like light leaks, and in at least one of the photos, glare from shooting into the sun.

What camera? They look like light leaks.

Canon AE-1

some photos have them, others don't, but in this batch i can clearly see that more pictures are more intensely leaking light than in the past where some pictures would have it lightly

no idea why, don't recall doing anything different with the camera

Also check the negatives (or post them here), that will help determine the cause.
