graininess

Graininess occurs when clumps of individual grains are large and irregularly spaced out in the negative. They are visible to the naked eye in the finished print, particularly enlargements, as sand-like particles. When this occurs, the picture appears grainy. Graininess in digital images is caused by noise, which usually appears in shadow areas and is generally unwanted and unattractive.

Photo Tips

graininess

The character of a photographic image when, under normal viewing conditions, it appears to be made up of distinguishable particles, or grains. This is due to the grouping together, or clumping of the individual silver grains, which are by themselves far too small to be perceived under normal viewing conditions.
