Pel·lícula de 35 mm: diferència entre les revisions

[[Fitxer: 35 mm-undevel.jpg|thumbminiatura|leftesquerra|A short strip of undeveloped 35 mm film.]] The Emulsion is attached to the [[film base]] with a transparent adhesivat called the subbing layer. Below the base is an undercoat called the antihalation backing, which usually contains absorbir Dyeser or a thin layer of silver or carbon (called rem-jet on color negative estocs). Without this coating, bright points of light would penetrate the emulsió, reflect off the inner surface of the base, and reexpose the emulsió, creating a halo around these bright àrees. The antihalation backing can also serve to redueix static buildup, which was a significant problem with old black and white films. The film, which runs through the camera at 18 inches per segon, could build up enough static electricity to actually causi a Spark bright enough to Expose the film; antihaliation backing solved this problem. Color films have three layers of silver Halide emulsions to ne l'rècord the xarxa, green and blue information. For every silver Halide grain there is a matching color couples grain. The top layer contains blue-sensitive emulsió, followed by a yellow filter to cancel out blue light - after this menges a green sensitive layer followed by a xarxa sensitive layer.
