Film Directors From New York City

A film also called a movie, motion picture, moving picture, picture, photoplay or (slang) flick is a work of visual art that simulates experiences and otherwise communicates ideas, stories, perceptions, feelings, beauty, or atmosphere through the use of moving images. These images are generally accompanied by sound and, more rarely, 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.

Recording and transmission of film

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.

Before the introduction of digital production, series of still images were recorded on a strip of chemically sensitized celluloid (photographic film stock), usually at the rate of 24 frames per second. The images are transmitted through a movie projector at the same rate as they were recorded, with a Geneva drive ensuring that each frame remains still during its short projection time. A rotating shutter causes stroboscopic intervals of darkness, but the viewer does not notice the interruptions due to flicker fusion. The apparent motion on the screen is the result of the fact that the visual sense cannot discern the individual images at high speeds, so the impressions of the images blend with the dark intervals and are thus linked together to produce the illusion of one moving image. An analogous optical soundtrack (a graphic recording of the spoken words, music and other sounds) runs along a portion of the film exclusively reserved for it, and was not projected.

Contemporary films are usually fully digital through the entire process of production, distribution, and exhibition.

Etymology and alternative terms

The name "film" originally referred to the thin layer of photochemical emulsion on the celluloid strip that used to be the actual medium for recording and displaying motion pictures.

Many other terms exist for an individual motion-picture, including "picture", "picture show", "moving picture", "photoplay", and "flick". The most common term in the United States is "movie", while in Europe "film" is preferred. Archaic terms include "animated pictures" and "animated photography".

"Flick" is in general a slang term, first recorded in 1926. It originates in the verb flicker, owing to the flickering appearance of early films.

Common terms for the field in general include "the big screen", "the silver screen", "the movies", and "cinema"; the last of these is commonly used, as an overarching term, in scholarly texts and critical essays. In early years, the word "sheet" was sometimes used instead of "screen".

History

Precursors

The art of film has drawn on several earlier traditions in fields such as oral storytelling, literature, theatre and visual arts. Forms of art and entertainment that had already featured moving and/or projected images include:
* shadowgraphy, probably used since prehistoric times
* camera obscura, a natural phenomenon that has possibly been used as an artistic aid since prehistoric times
* shadow puppetry, possibly originated around 200 BCE in Central Asia, India, Indonesia or China
* The magic lantern, developed in the 1650s. The multi-media phantasmagoria shows that magic lanterns were popular from 1790 throughout the first half of the 19th century and could feature mechanical slides, rear projection, mobile projectors, superimposition, dissolving views, live actors, smoke (sometimes to project images upon), odors, sounds and even electric shocks.

Before celluloid

The stroboscopic animation principle was introduced in 1833 with the stroboscopic disc (better known as the phénakisticope) and later applied in the zoetrope (since 1866), the flip book (since 1868), and the praxinoscope (since 1877), before it became the basic principle for cinematography.

Experiments with early phénakisticope-based animation projectors were made at least as early as 1843 and publicly screened in 1847. Jules Duboscq marketed phénakisticope projection systems in France from circa 1853 until the 1890s.

Photography was introduced in 1839, but initially photographic emulsions needed such long exposures that the recording of moving subjects seemed impossible. At least as early as 1844, photographic series of subjects posed in different positions have been created to either suggest a motion sequence or to document a range of different viewing angles.
