3-17. BLEACHED IMAGE
A bleached image (see figure 3-18) is caused by leaving the film in a freshly-
mixed fixing solution too long or at a temperature that is too warm.
3-18. LEAD-FOIL IMAGE
A lead-foil image (see figure 3-19) occurs when the embossing pattern from the
lead foil backing appears on the radiograph. The embossing pattern consists of raised
diamonds across both ends of the film. This happens when the film is put in backwards.

3-19. NO IMAGE
No image may result if no current was passing through the tube at the time of
exposure or if the film was placed in the fixing solution before it was placed in the
A reticulated film appears as a network of wrinkles or corrugations on the
emulsion of the x-ray film. When reticulation occurs, the finished film has a netlike or
puckered appearance resulting from swelling of the film's gelatin. Swelling is caused by
sudden changes in temperature during processing, as in the transfer from a cool fixing
bath to warm wash water or from a warm rinse water to a cool fixing bath.
