Hey guys so I'm new to film photography. I just bought a used Canon Rebel G with two lenses. I have used two rolls of film so far and so the other day i took them to Costco to get them developed (I went there because it was cheap) and when i picked up the pictures today i found a line running across all the pictures at the top. I have limited knowledge in this field so far but I'm guessing that this is a result of the printing process because i couldn't see the same lines on the negatives. I am hoping that It isn't the camera but let me know what you guys think. Thanks.
