Density produced on a negative, print or trannie by chemical processing or accidental exposure to light, caused by 1. exposure to non image-forming light (possibly: opening the camera back in daylight), 2. too much handling in air during the development process, 3. over-developed, 4. outdated film or paper, or 5. storage of film or paper in a hot, humid place. (see Outdated & Over development)
Produces an overall veil of density on a negative or print, which does not form part of the image. It can be achieved by chemicals or exposing the sensitive material to light.
Darkening or discoloring of a negative or print or lightening or discoloring of a slide caused by exposure to nonimage-forming light to which the photographic material is sensitive, too much handling in air during development, over-development, outdated film or paper, or storage of film or paper in a hot, humid place.
