Possible causes:
•
X-rays directed far from the medial section of the film
•
Low fluid level, with subsequent partial development of the film
•
Two or more films one close to the other in the developer.

Possible causes:
•
The film has been in the warehouse for too long (check expiry

When the film is excessively compressed and the air is dry,
electrostatic electricity can be released so it can run down to
compression points, where black marks form.

The scattering of developing or fixing fluid on the film before
development and fixing procedures causes spots on the X-rays; these
spots are:
•
Dark if caused by the developing fluid
•
Light if caused by the fixing bath.

If the film is kept in a warm water bath too long (for instance, all
night), the emulsion can soften and partially come off the base of the
film. After development, the film will be scratched.
