Graininess Is A Quality Of A Photograph That Is Determined By The Size And Shape Of The Grains Of Silver Halide Crystals That Make Up The Image

Graininess is a quality of a photograph that is determined by the size and shape of the grains of silver halide crystals that make up the image. It is affected by the film’s speed (ASA or DIN), development time, and temperature. Faster film, longer development times, and/or higher temperatures produce finer grained photographs with less apparent graininess.
