... the image silver is embedded in a thin layer that may consist of albumen, collodin, or gelatin.

CONT

In the chromogenic processes, three selectively light sensitive layers in the silver halide emulsion are exposed to light. Initially, a black and white, silver halide, latent image is chemically developed to form a negative on all three layers. During this stage, the developer used to convert the exposed silver halide to metallic silver becomes oxidized. The oxidized developer combines with color couplers initiating the selective formation of cyan, magenta and yellow dyes within discrete layers of the emulsion. The image silver is then bleached and unexposed silver halide is removed by fixing.

DEF

Image with density variations derived from the differential scattering power of microscopic bubbles(vesicles) formed in a transparent layer as when a light sensitive diazo compound in a gelatin coating on a transparent support is exposed behind a line negative and immersed in water.

Record 3 1985-12-16

English

Subject field(s)
  • Micrographics
DEF

a layer usually made of gelatin, applied to the side of the film base opposite that of the emulsion to prevent curl. It is comparable to the emulsion layer in thickness and is not removed in processing.(Antihalation or other layers removed in processing are excluded from this definition).

French

Domaine(s)
  • Micrographie
DEF

couche, ordinairement constituée de gélatine, appliquée sur le côté du support opposé à l'émulsion, afin d'empêcher l'incurvation du film. Son épaisseur se compare à celle de l'émulsion et elle n'est pas éliminée au cours des traitements. (Les couches anti-halo ou autres qui sont éliminées au cours des traitements ne sont pas incluses dans cette définition).

English

Subject field(s)
  • Aeroindustry
CONT

With the D-HUD, a form of holographic recording is used to produce a thin-film lens, covering the whole area of the curved combining glass.(...) This thin-film lens is produced by the use of a laser which records, photographically, a form of diffraction grating within a layer of gelatin which is coated onto the curved combining glass. After processing, the thin film lens is covered by a second glass layer to form a sandwich, with the "lens" formed by changes in the refractive index of the gelatin layer, providing the effect of a diffraction grating.

French

Domaine(s)
  • Constructions aéronautiques
CONT

Ce nouveau collimateur fait appel à une forme d'enregistrement holographique qui crée une lentille à couche mince recouvrant toute la surface de l'optique de mélange. (...) Cette lentille à couche mince est créée par un laser qui enregistre photographiquement une sorte de réseau de diffraction dans une couche de gélatine appliquée sur l'optique de mélange, elle-même recouverte d'une seconde couche de verre formant sandwich.

CONT

A roll film consists of a length of celluloid, coated with a sensitive emulsion on one side and a layer of plain gelatin on the other to reduce its tendency to curl.
