-Grains - exposed and developed silver halides which have formed black metallic silver grains, producing the visible photographic image.
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 colored starch grains in an Autochrome plate
Autochrome is an additive color 'screen-plate' process: the medium contains a glass plate, overlaying random mosaic of microscopic grains of potato starch, ...
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.
Vegetation or grains of sand for example, are much ...
Wildlife with medium format: For very long wildlife photography, 35mm format is much better to use than medium format cameras. Longer and faster lenses in 35mm makes it easier to shoot wildlife.
The silver that forms the developed image comes from a reduction of the individual silver halide grains in the film emulsion. This process is called chemical or direct development.
How are grains shaped? How thin are the layers? Thinner layers generally suffer less from irradiation and other blurring effects.
Development changes the silver in the emulsion to metallic grains, the faster the film the larger the grains. Development controls contrast. Film speed Is not affected by development.
Microscopic grains of potato starch were dyed red, green, and blue-violet, then mixed evenly and coated onto a sheet of glass. A black-and-white emulsion was then flowed over this layer.
If this doesn't remove all the grains of sand, try Step Two. Gently...GENTLY... use a brush to remove them. A sable or mink brush is best since you don't want to scratch your delicate camera or lens.
An image formed by the changes to the silver halide grains in photographic emulsion on exposure to light. The image is not visible until chemical development takes place. The invisible image left by the action of light on photographic film or paper.
The ideal exposure depends on the size of the light-sensitive grains in the film. A larger grain is more likely to absorb light photons than a smaller grain. The size of the grains is indicated by a film's speed, which is printed on the canister.
Although, while your monitor may have thousands of pixels, even the lowest quality film will have millions of grains. For the photographer the issue is not so much the number of grains as the size. Grain size is directly related to film speed.
To increase the sensitivity of films, manufacturers use larger crystals, or grains, of silver halide-the light-sensitive part of a film emulsion.
The faster films have a more prominent grain structure the individual grains clump together to form spots that are visible to the naked eye, especially when you blow the photo up to A4 or larger from a 35mm negative.
The sequence runs as follows: the larger the film's grains, the faster the film, the less light exposure needed. Therefore, highly defined and detailed pictures such as portraits are generally taken on finely grained slow film.
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.
Tiny red, green, and blue grains on the inside surface of a CRT monitor that are illuminated when an electron beam is directed toward them.
PhotoCD:
A popular storage method for digital images developed by Kodak.
It likely will help to a reasonable degree, but dust and particularly pollen grains have an amazing ability to "fuse" to your sensor and no amount of shaking (or brushing) will get rid of it.
Faster film is faster in large part because the silver halide grains are physically much larger. Unfortunately this mean that faster film is also more obviously grainy than slow.
T-Grain technology Trademark for patented Kodak film emulsion technology used in all Kodak Advanced Photo System films; uniquely shaped grains that align better than conventional silver crystals, ...
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, ...
These silver grains are typically microscopic, but they can clump together in certain films or under certain development conditions. When they clump to the extent that they become visible, the picture appears grainy.
Granularity
Objective term describing the amount that silver halide grains have clumped together within the emulsion.

Great attention must be paid to every minute detail, down to the grains of pepper in a dish and to the bubbles on top of a cup of coffee. Each photograph can require four hours of shooting time, if not more, so plan adequate time for a photo shoot.
Sealable bags are great to travel with, cleaning brushes to get those stray grains off your camera can be useful and cleaning clothes are helpful.
Substrate coated with emulsion containing light sensitive silver halide grains.

Compact Disk type storage technology developed by Kodak in the early 1990s.
When a film negative (especially from sensitive film) is enlarged onto photographic paper (in order to make a print), the tiny grains get enlarged too, and become visible.
There can be noises (distortion) in the image such has color grains when taken in a low light setting. Enhancing the contrast will help reduce it. As well the camera may be fixed to take images with low contrast levels.
Buildings photographed at night will give a very different look and using a tripod to capture the picture gives far better results than increasing the ISO and using a higher shutter speed, the resultant image will have a lot of grains and colors and ...
I like to change lenses, and Im still waiting for digital cameras to allow photographers to change lenses under those conditions without going through bloody hell or getting grains of dirt on the sensor.
With my 4x5, I can have a flower that's a quarter of an inch in the transparency, and when I blow it up to 40 by 50, I can count pollen grains.
need to mess around with focusing when I am trying to concentrate on what is available in front of me; and secondly, it often throws the focus out ever so slightly, which helps smooth out the million pinpricks of reflected light from the sand grains.
