Aluminium is the most common metal used for deposition, but other metals such as nickel and chromium are also used. The metal is heated and evaporated under vacuum. This condenses on the cold polymer film, which is unwound near the metal vapour source. This coating is much thinner than a metal foil could be made, in the range of 0.5 micrometres ...
Photographic emulsion is a light-sensitive colloid used in film-based photography. Most commonly, in silver-gelatin photography , it consists of silver halide crystals dispersed in gelatin . The emulsion is usually coated onto a substrate of glass , films (of cellulose nitrate , cellulose acetate or polyester ), paper, or fabric.
Type 1 photosensitive anodized aluminum is anodized aluminum that has been impregnated with a silver compound which, when exposed to a light source, creates an activated latent image. [5] Upon development [ 6 ] and fixing [ 7 ] a black, silver-based image is formed inside of the metal.
Panchromatic negative film is used in the camera as the rear component of a bipack in which the front film is a positive yellow dye image of the background scene. This yellow dye image is exposed on the negative by the blue light from the backing areas, but the yellow light from the foreground passes through it and records an image of the ...
Tabular-grain film is a type of photographic film that includes nearly all color films, and many black and white films like T-MAX films from Kodak (with Kodak's T-grain emulsion), Delta films from Ilford Photo and the Fujifilm Neopan films. The silver halide crystals in the film emulsion are flatter and more tabular (hence T-Grain).
Celluloids are a class of materials produced by mixing nitrocellulose and camphor, often with added dyes and other agents.Once much more common for its use as photographic film before the advent of safer methods, celluloid's common present-day uses are for manufacturing table tennis balls, musical instruments, combs, office equipment, fountain pen bodies, and guitar picks.
Instant films with different view and expose sides had, as seen from the view side, from the front towards the back of the film, in layers: A backing layer, a clear polyester layer, a mordant to receive the image in the film, a titanium white light reflecting layer, a carbon black opaque layer, a releaser for the cyan dye, an emulsion sensitive ...
Agfacontour Professional was (as of 2002 not anymore produced [1]) a special emulsion sheet film which, after exposure and development in the Agfacontour developer, produced direct equidensities. Agfacontour was introduced in 1970 by Agfa-Gevaert to produce equidensities by a direct, one-developing-step process.
