Cinematography is the recording of photographic images for cinema. Like other still photography, it includes making lighting and camera choices. However, the pictures move. A person who specializes in cinematography is called a cinematographer.
The word cinemetography come from the Greek words kinema - κίνημα, meaning "movement" and graphein - γράφειν meaning "to write".
Cinematographers use a lens to focus reflected light from objects. This light makes an image that is used by an image sensor or a light-sensitive material inside a movie camera. These images are created one after another and saved for later processing and viewing as a motion picture. When using and electronic image sensorm the image creates an electrical charge for each pixel in the image. These are processed and stored in a video file. This file can later be processed or shown. Images captured with photographic emulsion creat a series of invisible images on the film stock. Chemicals are used to "developed" this into visible images. The images on the film stock are projected for viewing the motion picture.
