I have noticed recently that one film magazine has irregular spacing between frames, what could be causing the problem?
Irregular spacing can be caused by many factors.
1. The start arrow on the film is not
properly lined up with the start arrow on the insert.
2. Changing film manufactures and not
changing to that manufactures take up spools. Each film manufactures spool size
3. The film magazines may need servicing.
4. Ilford HP-5 black and white has it owns
start mark indicated as an oblong line next to the start arrow on the insert.
