 Cinematography. Cinematography is the science or art of motion picture photography by recording light or other electromagnetic radiation, either electronically by means of an image sensor, or chemically by means of a light sensitive material such as film stock. Cinematographer views lens to focus reflected light from objects into a real image that is transferred to some image sensor or light sensitive material inside a movie camera. These exposures are created sequentially and preserved for later processing and viewing as a motion picture. Capturing images with an electronic image sensor produces an electrical charge for each pixel in the image, which is electronically processed and stored in a video file for subsequent processing or display. Images captured with photographic emulsion result in a series of invisible latent images on the film stock, which are chemically developed into a visible image. The images on the film stock are projected for viewing the motion picture. Cinematography finds uses in many fields of science and business as well as for entertainment purposes and mass communication. The word cinematography is based on the Greek words.
