Grain is a defect in film photography where the particles - normally clumps of silver halide crystals - of the film emulsion appear.
Grain is usually worse in faster films, and on smaller negative formats.

Overdevelopment promotes clumping in even fine-grain films, which is why pushed films (extended time in the first developer to increase the effective ISO) will always generate additional grain. But it's a relative matter.

Grain   The sand-like or granular appearance of a print, slide, negative, or digital image. Grain becomes more noticable with higher ISO settings, the degree of enlargement or length of exposure time.

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 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.

Grain. The particles of silver that make up a photographic image.
Grainy. Describes an image that has a speckled look due to particles of silver clumping together.

grain (gr)
(1) in paper, the direction in which the majority of the fibers lie; (2) smallest unit of weight used in American system of measuring based on the weight of a grain of wheat equal to 0.

grain
In a photograph, grain can be thought of as the amount of noise in the image. On photographic film it is the inaccuracy in the recording of the image due to the clumping of the silver atoms, present after exposure and development.

Grain. Irregularly shaped, microscopically small clumps of black silver making up the processed photographic silver halide image. Detectable on enlargement, particularly if the film emulsion was fast (ISO 1000 or over) and overdeveloped.

Grain: 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.

Grain
Silver particles that remain on the film after processing to form an image. Usually, the faster the film, the coarser the grain, the less the Definition.

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.

Grain: Film To Digital
In a film-based environment, grain became creatively exploitable and could be an aesthetic element in a picture. Grain was anticipated, and pictures were made with that expectation.

Grainy high speed B/W film negative
Film speed is roughly related to granularity, the size of the grains of silver halide in the emulsion, since larger grains give film a greater sensitivity to light.

Grain of Sensia (old version)/Provia 200 and 400 is a bit poor - better off pushing the 100 one stop or using Fuji 800 print. I can't speak for the new version of Sensia, Sensia II, since I have only used the 100 (no complaints).

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 grainyness of the sensor, although it is as important as the resolution to determining how much detail is captured, is in part dependent on the size of the sensor, and on the resolution of the camera.

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.

Film grain is the small speckles that show up on photographs. Film contains tiny granules of light sensitive material. The more sensitive the film is, the larger these granules are.

Less film grain
Clearer images
Better color
So, while it might seem like larger negatives are always better, that isn't necessarily the case. While larger film formats provide better results, they are also more expensive.

There's a grain of truth in both sides of this question, actually. Yes, JPG Compression does throw out information in your picture. The good news is, most of the time, you're not going to be able to tell the difference.

"The tight grain and color reproduction of Velvia have always provided great results," says Kay. "I suppose that's why every landscape photographer I know still uses film.

I like the grain, it gives the pic a infrared film grain effect from back when film was cool. nice treatment!

Cassegrain Telescope devised by Cassegrain in which an auxiliary convex mirror reflects the magnified image, upside down, through a hole in the center of the main objective mirror - i.e., through the end of the telescope itself.

What's with that grain and mottling?
Say you're tuning a radio to a station with a weak signal. You turn up the volume and hear static. Why? By amplifying the signal, you're also amplifying unwanted stray electronic bits: audio noise.

Typically, noise/grain is not a problem in this type of image. We recommend that you use ISO 200, or 400. The important point is that you don't need a very fast ISO; in fact super-fast ISOs may overexpose the firework display.

Now consider the grains during the second exposure. If the second exposure is fairly intense, latent image specks form on the surface of the grains from region A.

The Agfa produces grainy, dim photos with the #87C and #87 filters because of the effectiveness of its hot-mirror filter and limitations on how long the shutter can be left open, but the Nikon 950 produces wonderfully bright, clear images.

ISO 400-3200-Heavy grain and considerable contrast.
Color Negative Films
The same rule applies to negative color films as black and white films. The lower the ISO number, the finer the grain.

Noise appears as a grain or as numerous tiny specks. When the specks vary in tone only, the noise is referred to as luminance noise. Figure 1 shows a 100% crop of an image that has primarily luminance noise.

In order to prevent grains in your photo try to increase the exposure time or aperture size so that more light can enter the camera. At the same time select a lower ISO level in order to maintain your desired level of exposure.

Kodachrome 25 was a fine grained film with fairly accurate color reproduction and good color saturation. Over the last 8 years or so I used Fuji Velvia and Fuji Provia F ISO 100 transparency films for almost all of my 35mm photography.

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?

Comparing the size of photosites in digital cameras to that of film grain yields some interesting results. My Nikon D2x has a sensor that measures 23.7 x 15.

Most mirror lenses are of either a Schmidt-Cassegrain design or a Maksutov-Cassegrain design. The difference is in the shape of the corrector plate.

Forget the concern that a faster film produces more grain and is therefore less desirable.

The bigger the image got, the more grainy, unfocused and often distorted it would become, meaning that taking a favorite image and turning it into a work of art you'd be proud to hang on your wall was often more easily said than done.

Digital noise is often equated with excessive film grain in analog photography.

The higher you set the ISO, or the faster the film you use, the grainier and noisier your photo gets, the less saturated the colors, the lower the definition. In other words, the sacrifice for being able to take photos in lower light is quality.
