Emulsion: The light-sensitive material layer that is coated used in the producing films and printing papers.
Exposure: The amount of light that is allowed to reach film or printing paper.
Light-sensitive material, traditionally film though now often a digital sensor, that records the image created by the light. Most cameras use roll film, cassettes, or individual sheets.
The photo-sensitive material called photo-resist coated on the wafer goes into an exposed state by absorbing a single photon.
The act of letting light fall on a light sensitive material
2. The amount of light that passes through a lens (either a camera or photographic paper) to form an image.
Woodburytype--a photomechanical process in which the completed prints are not made with light-sensitive materials.
A photogram is a photographic image made (without a camera) by placing objects directly onto the surface of a photo-sensitive material such as photographic paper and then exposing it to light.
A photograph is made by focusing some rays of light through a lens onto a light sensitive material of some sort where it is captured. In the case of film, it is captured through a chemical process.
Photodiodes, the tiny light sensitive materials used to measure the amount of light for each pixel on a CCD are essentially monochrome devices, that is they can't themselves tell the difference between different wavelengths of light.
But light-sensitive materials, whether film or digital sensors, have a problem when faced with high-contrast subjects. They have a limited ability to record such subjects.
a seamless, self-supporting all nickel printing stencil made by coating a metal base sheet with photosensitive material, exposing through the film negative, processing to eliminate the coating in the areas to be blocked in the stencil, ...
Initially, the holder used a roll of paper coated in the light sensitive material. This suffered from the appearance of the grain of the paper.
An ISO speed is a mathematical expression of a photosensitive material's sensitivity to light.
A darkroom is a workspace, usually a separate area in a building or a vehicle, made dark to allow photographers to use light sensitive materials to develop film and photographic paper to make photographic prints.
Lens - disc (s) of optical glass used to form an image of a subject on a sensitive material [The enlarger uses a lens just like a camera. Lens come in many different types. Think of a pair of glasses to see better or differently.
It is like any other kind of photography, but instead of using a lens, a very small hole used to project the image on the film or other light sensitive material. There's not much else to it.
Color film has three different layers of light-sensitive materials, which respond, in turn, to red, green and blue. When the film is developed, these layers are exposed to chemicals that dye the layers of film.
Expression used to indicate that the light sensitive material has been excessively exposed. This can be the result of light that is either too bright, or has been allowed to act for too long.
A solution used to make visible the image produced by allowing light to fall on the light-sensitive material. The basic constituent is a developing agent which reduces the light-struck silver halide to metallic silver.
Allowing too little light to reach a photosensitive material. Results in a "thin" or light image with negative material and a dark or "dense" image with reversal material or a digital sensor.

Exposed. A light-sensitive material that has received exposure to an image. Usually relates to the stage after exposure and before processing.
Export. To transfer text or images from a document to another format.

SAFELIGHT - A lamp, typically in a darkroom, that allows a person to view light-sensitive material without it being altered by the light.
(*) Overexposure -- Photosensitive material which has been exposed to too much light for a good image to form. Instead the image will be burned out and appear too white on a final print.
Batch numbers
Set of numbers printed on packages of sensitive materials to indicate common production coating.
Batch processing
The performing of a group of computer tasks at the same time.
In relation to photography's history, the camera obscura paved the way for images to be focused onto materials such as paper, metal or glass that were coated with light-sensitive materials.

Changing Bag: A light proof black fabric bag that permits film and other light-sensitive materials to be handled in normal room light. Has a double zipper on one end and two armholes with elastic sleeves on the other.
" But more often than not, the word exposure refers to the amount, and act, of light falling on photosensitive material (either the film or digital sensor).
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.
Latitude refers to the exposure tolerance of a photosensitive material.
Film: A negative or positive, photographic or lithographic record made on a light sensitive material.
