Film Stock

Film stock is nothing but photographic film for shooting and reproducing motion pictures. Its formation dates back to the time which witnessed the first introduction of transparent flexible film materials, discovered and refined for photographic use by George Eastman, Hannibal Goodwin and John Carbutt.

Prior to the initiation of Film stock, most motion pictures were made on paper roll films on an experimental basis. The problem with paper roll films is that they face tremendous problems at the time of development into a single continuous image, without the application of complex equipments. Moreover, paper films are most delicate in nature than the celluloid ones which are more permanent in nature.

Film stock can be classified into different types, but in reality, a raw film stock functions with the help of code numbers, depending upon the sensitivity of light.

A single piece of Camera Film stock is made up of high light-sensitive emulsion, producing effects when applied on a transparent and hard base. The emulsion consisting of silver halide particles suspended in gelatin colloids is applied in three layers in case of color films. When these particles come in contact with the interlayers and color couplers filtering definite light spectra, they result in the creating colored layers in the negative after developing the films.

Overall, Film stock forms an integral and inseparable part of contemporary motion pictures, enabling the film industry to produce picture qualities which are excellent and matchless. This is one of the trade secrets of modern film industry all over the world, which depends highly on Film stock for quality motion images.
