I just got back my first roll of film. It was a $2 roll of B&W shot on a Pentax K1000. Everything is alright except that a couple images (or maybe 3 or 4 images) are overlapped. Why does this happen? Here are the images 1. 2. An additional note: When there is no film loaded into the camera and I press the shutter, the initial "smack" is followed by what sounds like an "echo." It sounds somewhat like a swinging door you see going into bars in old Western movies.
