Cinematography and Film/Video Production

"Cinematography" refers to creating still images for use in motion pictures and, more recently, electronic video cameras. The lens on a film camera concentrates the scene's reflected light into a sharp image recorded by the camera's image sensor or other light-sensitive material. These photographs are taken in rapid succession and stored so they can be processed and viewed as a moving pictures later. When an image is captured using an electronic image sensor, an electrical charge is generated for each pixel. This information is then processed and saved in a video file for later use. Capturing an image with photographic emulsion creates a succession of latent images on the film material, which are only revealed through a chemical "development" process. Moviegoers see the same flick repeatedly by projecting still images from the film stock. As well as its obvious entertainment and dissemination value, cinematography has many practical applications in the scientific and commercial worlds.
