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."
A subjective measure of the visible clumping of grains in an emulsion. Different from Granularity.
Clumps of silver halide crystals in the emulsion which are visible to the human eye because of spaces between the crystals.
The impression of non-uniformity in the image which is produced on the consciousness of an observer by the granular structure. It is most noticeable in areas of uniform density of middle values. It becomes less apparent in light and in dark areas and in areas that contain considerable detail. Graininess is subjective in nature.
the sand-like or granular appearance of an image. Graininess becomes more pronounced with faster film and the degree of enlargement. In digital imaging, graininess may occur as a result of printing an image, the pixel resolution of which is too coarse, or as a result of using a printer with poor dot resolution.
The visual appearance of granularity.
The sand-like or granular appearance of a negative, print, or slide. Graininess becomes more pronounced with faster film and the degree of enlargement.
1. Consisting of grains, coarsely textured, granular. 2. Defect in a paint surface, which appears rough, as though sand or some other material had become mixed with it.
in an enlarged image, a speckled or mottled effect caused by oversized clumps of silver in the negative
