Film stock

Description

Film stock is an analog medium that is used for recording movie or animation. It is recorded on by a movie camera, developed, edited and projected onto a screen using a movie projector. It is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast and resolution of the film.

The emulsion will gradually darken if left exposed to light, but the process is too slow and incomplete to be of any practical use. Instead, a very short exposure to the image formed by a camera Lens is used to produce only a very slight chemical change, proportional to the amount of light absorbed by each crystal. This creates an invisible latent Image in the emulsion, which can be chemically developed into a visible photograph. In addition to visible light, all films are sensitive to x-rays and high-energy particles. Most are at least slightly sensitive to invisible ultraviolet (uv) light. Some special-purpose films are sensitive into the Infrared (ir) region of the spectrum.

Film stocks come in various types, each with its own characteristics, sensitivity to light and color reproduction. Different film stocks may be chosen based on the specific requirements of a project such as the desired visual style, sensitivity to low light conditions or color temperature. Some film stocks are designed for black and white cinematography, while others are intended for color.

Film stock is the raw material out of which photographic images are produced. There are many different types of film stock, often distinguished by the “emulsion” Coating on each side of the film base. Film stock comes in several varieties, including negative and positive print stocks.

The negative variety is used in professional production and commercial photography, while print stocks are used to make prints for still photography or motion picture film. Negative film stocks are available in black-and-white and color varieties, while print stocks are typically only available in black-and-white. Color print stocks produce color photographs by adding dyes or pigments during processing, while black-and-white print stocks produce black-and-white photographs through a silver halide process.

Film stock intermediate and print stocks are used to create still images, motion pictures and digital film. These films are distributed to theaters and movie houses where they are projected in front of an audience. Film stock Intermediate is a material that is used to make prints that can be used for movies. There are two types of Film stock, color positive and color negative. Both are used for photography, but the colors are reversed for each film type. film stocks have different colors to represent specific wavelengths of light. The color positive film has a blue base and contains red, green and blue dyes along with a silver halide coating. The color negative uses a red base with cyan, magenta and yellow dyes which replaces the silver halide in the emulsion layer.
