X-ray photography can make the film produce the following functions.

In X-ray photography, the film will become blurred.

When the film is in normal photographic processing, some metallic silver in the unexposed part is reduced to a certain density, which is called haze or fog density of the film. Among the red, green and blue layers, the fog density of color film is the highest. If the fog is too heavy, the contrast of the image will be reduced, which will affect the level and clarity of the image.
