Clumps of silver halide crystals in the emulsion which are visible to the human eye because of spaces between the crystals.

MINIMIZING GRAININESS As you know, most black-and-white photographic images on film emulsions are made of fine grains of silver. Because of this silver grain structure, enlarge- ments, especially large ones, may appear "grainy.
Graininess
Graininess is a descriptive term used to characterize the level of film grain (emulsion particles on the film frame) visibly apparent to the human eye.

Graininess A term particular to film, it refers to the appearance of grain (the structure of a film's coating or emulsion) in a print, transparency or negative.
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.
Graininess - a mottled effect in the negative
Burning - in adding light to certain parts of the image by extra exposure while the rest of the image is protected from the enlarger light ...
graininess
an effect seen in the print as randomly occurring light and dark specks or grains, due to roughing of the edges of halftone dots, random specks of ink between dots, discontinuous ink films, ...
Graininess ( Grain )
The granular appearance of a negative, print, or slide. Graininess becomes more pronounced with faster film and the degree of enlargement. The sand-like or granular appearance of a negative, print, or slide.

The graininess of the images becomes much more prominent at ISO 800, as you would expect. Again, Canon seems to have put more effort into reducing chroma noise (with the smearing of color that this brings), than luminance noise.
The graininess in an image that results when the pixels are too big, relative to the size of the image.
PMS:
Short for Pantone Matching System; a trademarked standard for specifying and producing spot colors using proprietary ink mixes.
Some people take this "mimicry" a step further, though, and try to add graininess to the photo. Grain, in some quarters, has become an artistic statement. I've always found this particular conceit to be rather amusing. Why?
The color is soooo amazingly lifelike, I do notice a little graininess with the 400F though. I have tried Fuji sensia 200 and Kodak Elite chrome ex color. I will NEVER shoot a train with Elite chrome ex-color again! ...
The ASA and ISO film speed scales are important because they determine photo quality: the graininess of a finished photo. The sequence runs as follows: the larger the film's grains, the faster the film, the less light exposure needed.
Graininess in photos, or rather the perception of excess grain, has been virtually eliminated from today's films - fast ones and slow ones. You want to use fast film so you can "stop" the action even in shaded areas of the field.
Graininess: Term used to describe the grainy appearance of a photograph caused by the silver grain clumps or dye images, which form the photographic image.
Ground glass: Translucent screen used for viewing and focusing in large format photography.
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.)

Just as with its film counterpart, an image sensor will exhibit "noise" (comparable to "graininess" in film) at the higher ISO speeds.
Noise is a term used to describe the graininess, usually associated with using high ISO settings or high speed films.

Graininess The sand-like or granular appearance of a negative, print, or slide. Graininess becomes more pronounced with faster film and the degree of enlargement.
Many "point and shoot" digital cameras however, render unsatisfactory graininess or muddied color results when the ISO is set for values approaching 400 and greater.
The effect can be compared to graininess in conventional film. For best picture quality ignore this type of zoom since it is no more than a clever marketing trick. It doesn't do anything useful other than throwing away part of your image.
Kodak has defined a "Print Grain Index" (PGI) to characterize film grain (color negative films only), based on perceptual just noticeable difference of graininess in prints.
The selection of camera and lens can determine the image characteristics such as sharpness, tonal range, field of view, and graininess of the final print.
Changing the ISO will change the light sensitivity, but will also change the graininess of the photo. Read this article if you often shoot at low lighting, or if your photos come out grainy often.

This term refers to the graininess of high ISO images taken in the digital format.
Luckily there are now editing software programs that specifically eliminate noise and sharpen a photograph taken under questionable conditions.
This is a measure of a film's relative "graininess," with each successive number indicating twice as much grain as the preceding. For example, an RMS rating of 11 is considered twice as grainy as one with an RMS of 10.
Capture One Pro: At 33% of it's noise reduction did a fair job. There is almost no color noise. There is above average graininess but excellent detail retention.
As a rule, more sensitive media (higher ISO numbers) will yield images with more grain. In some cases, the graininess can become extreme, even affecting image quality. While often unwanted, this is sometimes used to enhance a certain 'feel'.
NOTE - Remember that the above information assumes you begin with a technically good photograph of proper exposure, focus, and clear of graininess.

The downside to high ISO speeds is the resulting graininess of the image. Starting with 1600 will provide a good foundation while learning astrophotography. After you become proficient, bump the ISO down to 400 for crystal clear images.
A lower ISO number means that the film needs more light to take a picture than does film with a higher ISO, but with the trade off of graininess or noise and colour saturation.
Minute metallic silver deposits form a photographic image. The individual grain is never visible, even in an enlargement, but the randomness of their distribution in the emulsion can cause over-lapping, or clumping, which can lead to graininess in ...
Nighttime shooting often heightens the effects of noise because the darkness of low-light pictures makes it easier to see. When you edit your pictures, you'll likely want to use noise-reduction software, which helps minimize graininess and makes ...
The higher this number the more quickly the camera captures light - it is a holdover from the days when you purchased faster film. Higher ASA will also help you freeze action shots - but at the cost of some graininess. Good luck! ...
Keep in mind that changing each element not only impacts the exposure of the image but each one also has an impact upon other aspects of it (ie changing aperture changes depth of field, changing ISO changes the graininess of a shot and changing ...
A fellow photographer once observed that photographers tend to smell pictures rather than look at them, by which he meant that they were more interested in the graininess and sharpness of the image than the actual content of the image itself.
Keeping it low (like 100, unless your camera can do lower like 80 or 50 which is even better) will minimize graininess.
