EN: Grain:


Tiny clumps of silver crystals that form the photographic image during film development, their pattern is sometimes visible in the print. The faster the film, the more visible the grain--but even fast films are now very fine-grained.
Glossary of Photo Jargon for Travelers




The appearance or echoes of the silver crystals in film in the final negative or positive image. The larger the area of the grain in the film emulsion, the more sensitive the film is to light the more sensitive it is to light the faster it is. Larger grains are manifest in the image as mottled or salt-and-pepper clumps of light and dark tones, usually apparent in very fast films on visual inspection, in slow films upon extreme magnification. Grain is most easily seen as non-uniform density in areas sharing the same tone (such as a gray sky.).
