Hi, I just start to shoot film photo with Canon AE-1 Every time I develop the film, there are light leaked photos. It does not happen all of photos, but it happens quite often. Also, the light leak is located at center most of the time. Also, even though I did not open the back of my camera, some part of film came out blank. Is it my camera problem? or do I use it wrong? Can I fix this problem? I developed three rolls and it has same problem on every roll.
