Any small, hard particle, as of sand, sugar, salt, etc.; hence, any minute portion or particle; as, a grain of gunpowder, of pollen, of starch, of sense, of wit, etc.
The composite particles of any substance; that arrangement of the particles of any body which determines its comparative roughness or hardness; texture; as, marble, sugar, sandstone, etc., of fine grain.
To form grains, or to assume a granular form, as the result of crystallization; to granulate.
Minute crystals of silver halides in the light-sensitive emulsion of film that react when exposed to light, turning black, are called "grains." (See Graininess of film.)
(r) anisotropy introduced into rubber during processing operations.
An individual crystal in a polycrystalline metal or alloy; it may or may not contain twinned regions and sub grains.
Internal grain lines in or outside a diamond (part of the crystal orientation).
A speckled appearance in photos. In film photographs, grain appears when the pattern of light-sensitive silver halide particles or dye molecules becomes visible under magnification or enlargement. In digital images, grain appears as multicolored flecks, also referred to as noise. Grain is most visible in high-speed film photos and in digital images captured at high ISO settings.
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.)
The visible particles (grains) of metallic silver on the film image caused by large clusters of grains on the film emulsion.
The granular texture of a photograph caused by the clumping of the silver particles, which is usually more visible when the photograph is enlarged.
The silver halide crystals that compose a photographic emulsion.
the random pattern within the photographic emulsion that is made up of the final (Processed) metallic silver image. The grain pattern depends on the film emulsion, plus the type and degree of development. Film Speed
microscopic particles which are clustered together on film emulsion are known as grain. If these become visible upon projection, the film is descibed as "grainy."
The uneven texture in a developed photographic emulsion, resulting from the clumping of silver grains, and observed in a negative, print or transparency. Graininess is more pronounced with faster films, increased density in the negative and the degree of enlargement.
A particle of a mineral or rock, generally lacking well-developed crystal faces.
An individual crystal in a polycrystalline metal or alloy. The unit cells of a grain have an unique and distinct orientation.
An individual, small crystallite which is a part of a larger polycrystalline material made up of numerous grains.
Artifact of cinematographic production due to the finite size of film emulsion grains, especially with high sensitivity film stocks.
The sand-like, granular appearance of a negative, print or trannie. Graininess becomes more noticeable with fast films and increased size of enlargement.(Granularity: The amount of grain clumping that has occurred within an emulsion. Also referred to as graininess.) (see: Emulsion, Enlargement & Fast film,)
course dots that you can see in a picture. As the film's ISO increases, grain also increases.
This happens when an enlargement reveals visible grains of silver bromide on a print. Usually caused by improper development of film or by enlarging prints beyond the capabilities of the film. May also be caused by poor quality film. Faster ISO film has larger grains of silver bromide and thus cannot be enlarged as much as the slower films without revealing grain.
A description of the size of particles or crystals in rocks or sand. Coarse grained rocks have particles or crystals which are large (1 mm or more), and fine grained rocks have particles which are small (0.1 mm or less).
The sand or granular appearance of a negative or print. Grain becomes more pronounced on faster films and with the degree of enlargement.
A mechanically separate particle in the snow cover, may consist of several crystals.
Individual crystal in a polycrystalline material.
In petrology, that factor of the texture of a rock composed of distinct particles or crystals which depends upon their absolute size.
The sandy or mottled appearance of a picture or negative. This is a result of tiny clumps of silver crystals that form the photographic image during film development. The faster the film the more visible the grain, however even fast films are now fine-grained.
The term used to describe a granular appearance in a photograph. Grain is actually the image of the enlarged emulsion. The effect is more noticable in higher speed films, and in enlargements.
The size of the particles of silver in a photographic image. If these are fairly large and noticeable the image is said to be grainy. This can be the case if a fast film is used, if the lighting is insufficient, or if a very big enlargement is made from a small negative. Fine grained images are produced if lighting is good, slow film is used, and enlargement size is not too great in relation to the negative size.
In manufactured carbon and graphite product technology, a region in a carbon or graphite body that is identifiable as being derived from a particle or filler.
In prints, grain refers to an overall gritty-like fuzziness that becomes visible as an image is enlarged beyond a certain size. This varies with the speed and format of the film and the size of the enlargement or the extent of any cropping. In films, grain refers to the individual crystals of the light sensitive chemicals in the emulsion of the film. Fine grain films are generally considered “slower” requiring more time and/or more light for proper exposure, but give a much sharper image than larger grain “faster” films.
An aggregate (group) of individual crystals Bonding between grains (across grain boundaries) is less perfect than bonding within a grain.
Granularity of information; semantic depth.
Exposed and processed silver halides on the film emulsion that turn black and form miniature "grain" that make up the image on a piece of film. The equivalent efect at high ISO in digital photography -which is grainless- is "noise".
(1) The direction that the fibres in a sheet of paper run. Indicative of the direction in which paper is made on a paper machine. (2) In film terms, grain describes the textured effect of individual crystals of silver on the appearance of the image.
Referring to a region in a carbon or graphite body that is identifiable as being derived from a particle of filler.
Particles or discrete crystals which comprise a rock or sediment.
An individual crystal in a poly-crystalline metal or alloy.
The unidirectional orientation of rubber or filler particles occurring during pro- cessing (extrusion, milling, calen- dering) resulting in anisotropy of a rubber vulcanizate.
(4) crystals or multi-crystal fragments within a lithified matrix. For example, sand grains in sandstone and quartz grains in sand-sized particles.
An individual crystal in a polycrystalline metal or alloy; it may or may not contain twinned regions and subgrains; a portion of a solid metal (usually a fraction of an inch in size), in which the atoms are arranged in an orderly pattern.
A term used to describe tiny flecks of color (silver bromide) on a photographic print, usually caused by improper development of film.
a crystal (ordered arrangement of atoms).
The particles of silver that make up a photographic image.
(n.) See granularity
The individual crystal units comprising the aggregate structure where the crystalline orientation does not change. The grain boundary is where these individual crystal units meet.
A cluster of silver halide crystals, the basic physical element of density in a photograph.
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.
In general, a single crystal of a mineral. (In sedimentary rocks, a grain is a particle that is between 0.03 mm and 2 mm in diameter.)
The smallest component of a photographic image. A single particle of silver or dye cloud. Collectively, the size of those particles.
Minute metallic silver deposit, forming in quantity the photographic image. The individual grain is never visible, even in an enlargement, but the random nature of their distribution in the emulsion causes over-lapping, or clumping, which can lead to graininess in the final image. Also cross check with below for graininess. When a photographer talks about fine grained films, they are talking about the smallest distinguishable component of a print. The slower the ASA rating, the finer the grain, and the converse is also true.
Grain is the speckled texture you sometime see in prints made from fast film. The coarse dots do not show fine detail but can give an unusual creative effect. Use high speed colour film such as ISO 1600 to photograph flowers or landscapes for an artistic painterly effect.
A grain is a single particle of pollen.
In photography, the grain is the granular particles in photographic emulsion of an original print or negative. The printing process causes the grain to become more apparent than in the original.
clumps of silver-halide grains in film and paper that constitute the image. These grains are produced both in the exposure process (film grain) and in the development process (paper grain). Unlike film, the grain in printing paper is largely responsible for the image tone.
