MOTION PICTURES ARE MADE POSSIBLE BY PERSISTENCE OF VISION. ITS PRINCIPLES EXPLAINED WITH ANIMATION, DIAGRAMS. STUNT DRIVER ROLLS CAR OVER. GOOD SHOTS AUDIENCES, PATRONS ENTERING THEATRE, PROJECTION EQUIPMENT. PROCESS SHOT OF AUDIENCE WATCHING FILM.

Originally a public domain film from the Library of Congress Prelinger Archives, slightly cropped to remove uneven edges, with the aspect ratio corrected, and one-pass brightness-contrast-color correction & mild video noise reduction applied.

The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and/or equalization (the resulting sound, though not perfect, is far less noisy than the original).

Film, also called movie or motion picture, is a medium used to simulate experiences that communicate ideas, stories, perceptions, feelings, beauty or atmosphere by the means of recorded or programmed moving images along with other sensory stimulations. The word "cinema", short for cinematography, is often used to refer to filmmaking and the film industry, and to the art form that is the result of it.

The moving images of a film are created by photographing actual scenes with a motion-picture camera, by photographing drawings or miniature models using traditional animation techniques, by means of CGI and computer animation, or by a combination of some or all of these techniques, and other visual effects.

Traditionally, films were recorded onto celluloid film through a photochemical process and then shown through a movie projector onto a large screen. Contemporary films are often fully digital through the entire process of production, distribution, and exhibition, while films recorded in a photochemical form traditionally included an analogous optical soundtrack (a graphic recording of the spoken words, music and other sounds that accompany the images which runs along a portion of the film exclusively reserved for it, and is not projected)...

The individual images that make up a film are called frames. In the projection of traditional celluloid films, a rotating shutter causes intervals of darkness as each frame, in turn, is moved into position to be projected, but the viewer does not notice the interruptions because of an effect known as persistence of vision, whereby the eye retains a visual image for a fraction of a second after its source disappears. The perception of motion is partly due to a psychological effect called the phi phenomenon.

The name "film" originates from the fact that photographic film (also called film stock) has historically been the medium for recording and displaying motion pictures...

Persistence of vision traditionally refers to the optical illusion that occurs when visual perception of an object does not cease for some time after the rays of light proceeding from it have ceased to enter the eye. The illusion has also been described as "retinal persistence", "persistence of impressions", simply "persistence" and other variations. According to this definition, the illusion would be the same as, or very similar to positive afterimages.

"Persistence of vision" can also be understood to mean the same as "flicker fusion", the effect that vision seems to persist continuously when a stream of light is repeatedly interrupted for very brief instances and thus enters the eyes intermittently.

Since its introduction, the term "persistence of vision" has been believed to be the explanation for motion perception in optical toys like the phenakistiscope and the zoetrope, and later in cinema. However, this theory has been disputed even before cinema was introduced in 1895. If "persistence of vision" is explained as "flicker fusion", it can be seen as an important factor in the illusion of moving pictures in cinema and related optical toys, but not as its sole principle.

Early descriptions of the illusion often attributed the effect purely to imperfections of the eye, particularly of the retina. Nerves and parts of the brain later became part of explanations.

Sensory memory has been cited as a cause...
