Film grain or granularity is the random optical texture of processed photographic film due to the presence of small particles of a metallic silver, or dye clouds, developed from silver halide that have received enough photons. While film grain is a function of such particles (or dye clouds) it is not the same thing as such. It is an optical effect, the magnitude of which (amount of grain) depends on both the film stock and the definition at which it is observed. It can be objectionably noticeable in an over-enlarged photographic film photograph.

Famous quotes containing the words film and/or grain:
“If you want to tell the untold stories, if you want to give voice to the voiceless, you’ve got to find a language. Which goes for film as well as prose, for documentary as well as autobiography. Use the wrong language, and you’re dumb and blind.”
—Salman Rushdie (b. 1948)
“A peck of grain can make a friend; a bushel of grain can make a foe.”
—Chinese proverb.
