I shot a roll on a Minolta XG-1, and 8 of the 24 photos came back with blue bands along the edges. On some frames it appears on one side, on others both sides. What usually causes this on 35mm film, and how can I check whether the camera is the problem?

This is definitely edge-fogged film. We can’t say if the film was light-struck due to improper camera loading /unloading or camera light-leak or if the film was mishandled at the processing lab. All are suspect. Film cameras should be loaded and unloaded in subdued light.
You would be wise to test your camera to see if it is leaking light. Often the light seal at the edges of the hinged back become faulty. To test: Procure a tiny key-chain flashlight, one that stays on when switched. Place this lit flashlight in the film loading area and close the camera. Now retire to a closet or otherwise dark area. Examine the camera from all angles. If you don’t see light right away, stay in this dark place for 15 minutes. It takes that long for your eyes to dark adopt. This test works, if light can leak in, it can also leak out.
Best of luck discovering the cause!

Blue bands along the edges are most likely edge fogging from unwanted light reaching the film. Common causes include:
- a camera light leak, often from worn back-door light seals
- loading or unloading the film in bright light
- mishandling during processing
Because it only affects some frames, a light leak is a strong possibility, but the exact source can’t be confirmed without seeing the negatives.
A simple camera check is to test for leaks around the film door: put a small flashlight inside the camera’s film chamber, close the back, then inspect the outside in a very dark room after your eyes adjust. If you can see light escaping anywhere, the seals or back may be leaking.
Also try loading and unloading film in subdued light to reduce the chance of edge fogging from handling.
