Blurring can be caused by poor film-screen contact, patient movement, or poor centering of the primary x-ray beam.
If the distance between the object and the film is increased, you may get distortion or magnification of the image.
Static electricity tends to make linear dots or a tree pattern on a radiograph.
For good tables that list common technical errors in taking and developing x-ray films, see Bassert, Beal and Samples, McCurnin’s Clinical Textbook for Veterinary Technicians, 9thed. pp. 498-9, boxes 16-2 and 16-3.
