OR:

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

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

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

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

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. The advent of stereoscopic photography, with early experiments in the 1840s and commercial success since the early 1850s, raised interest in completing the photographic medium with the addition of means to capture colour and motion.

published about the idea to combine his invention of the phénakisticope with the stereoscope, as suggested to him by stereoscope inventor Charles Wheatstone, and to use photographs of plaster sculptures in different positions to be animated in the combined device. In 1852, Jules Duboscq patented such an instrument as the "Stéréoscope-fantascope, ou Bïoscope", but he only marketed it very briefly, without success. One Bïoscope disc with stereoscopic photographs of a machine is in the Plateau collection of the Ghent University, but no instruments or other discs have yet been found.

came about and provided hope that motion photography would soon be possible, but it took a few decades before it was successfully combined with a method to record series of sequential images in real-time. In 1878, Eadweard Muybridge eventually managed to take a series of photographs of a running horse with a battery of cameras in a line along the track and published the results as '' The Horse in Motion'' on cabinet cards. Muybridge, as well as Étienne-Jules Marey, Ottomar Anschütz and many others, would create many more

studies. Muybridge had the contours of dozens of his chronophotographic series traced onto glass discs and projected them with his zoopraxiscope in his lectures from 1880 to 1895. Anschütz developed his own Electrotachyscope in 1887 to project 24 diapositive photographic images on glass disks as moving images, looped as long as deemed interesting for the audience. Émile Reynaud already mentioned the possibility of projecting the images of the Praxinoscope in his 1877 patent application. He presented a praxinoscope projection device at the Société française de photographie on 4 June 1880, but did not market his ''praxinoscope a projection'' before 1882. He then further developed the device into the Théâtre Optique which could project longer sequences with separate backgrounds, patented in 1888. He created several movies for the machine by painting images on hundreds of gelatin plates that were mounted into cardboard frames and attached to a cloth band. From 28 October 1892 to March 1900 Reynaud gave over 12,800 shows to a total of over 500,000 visitors at the Musée Grévin in Paris.
