FILM

Film
From Wikipedia, the free encyclopedia
Film encompasses individual motion pictures, the field of film as an art form, and the motion picture industry. Films are produced by recording images from the world with cameras, or by creating images using animation techniques or special effects.

Films are cultural artifacts created by specific cultures, which reflect those cultures, and, in turn, affect them. Film is considered to be an important art form, a source of popular entertainment and a powerful method for educating — or indoctrinating — citizens. The visual elements of cinema gives motion pictures a universal power of communication. Some films have become popular worldwide attractions by using dubbing or subtitles that translate the dialogue.

Traditional films are made up of a series of individual images called frames. When these images are shown rapidly in succession, a viewer has the illusion that motion is occurring. The viewer cannot see the flickering between frames due to an effect known as persistence of vision, whereby the eye retains a visual image for a fraction of a second after the source has been removed. Viewers perceive motion due to a psychological effect called beta movement.

The origin of the name "film" comes from the fact that photographic film (also called film stock) had historically been the primary medium for recording and displaying motion pictures. Many other terms exist for an individual motion picture, including picture, picture show, photo-play, flick, and most commonly, movie. Additional terms for the field in general include the big screen, the silver screen, the cinema, and the movies.
History

Main article: History of film

Preceding film by thousands of years, plays and dances had elements common to film, scripts, sets, costumes, production, direction, actors, audiences, storyboards, and scores. Much terminology later used in film theory and criticism applied, such as mise en scene (roughly, the entire visual picture at any one time). Moving visual and aural images were not recorded for replaying as in film.

Near the year 1600, the camera obscura was perfected by della Porta. Light is inverted through a small hole or lens from outside, and projected onto a surface or screen, creating a moving image, but it is not preserved in a recording.

In the 1860s, mechanisms for producing artificially created, two-dimensional images in motion were demonstrated with devices such as the zoetrope, mutoscope and praxinoscope. These machines were outgrowths of simple optical devices (such as magic lanterns) and would display sequences of still pictures at sufficient speed for the images on the pictures to appear to be moving, a phenomenon called persistence of vision. Naturally the images needed to be carefully designed to achieve the desired effect, and the underlying principle became the basis for the development of film animation.

With the development of celluloid film for still photography, it became possible to directly capture objects in motion in real time. Early versions of the technology sometimes required a person to look into a viewing machine to see the pictures which were separate paper prints attached to a drum turned by a handcrank. The pictures were shown at a variable speed of about 5 to 10 pictures per second, depending on how rapidly the crank was turned. Some of these machines were coin operated. By the 1880s the development of the motion picture camera allowed the individual component images to be captured and stored on a single reel, and led quickly to the development of a motion picture projector to shine light through the processed and printed film and magnify these "moving picture shows" onto a screen for an entire audience. These reels, so exhibited, came to be known as "motion pictures". Early motion pictures were static shots that showed an event or action with no editing or other cinematic techniques.

Ignoring Dickson's early sound experiments (1894), commercial motion pictures were purely visual art through the late 19th century, but these innovative silent films had gained a hold on the public imagination. Around the turn of the twentieth century, films began developing a narrative structure by stringing scenes together to tell narratives. The scenes were later broken up into multiple shots of varying sizes and angles. Other techniques such as camera movement were realized as effective ways to portray a story on film. Rather than leave the audience in silence, theater owners would hire a pianist or organist or a full orchestra to play music fitting the mood of the film at any given moment. By the early 1920s, most films came with a prepared list of sheet music for this purpose, with complete film scores being composed for major productions.
The rise of European cinema was interrupted by the breakout of World War I while the film industry in United States flourished with the rise of Hollywood. However in the 1920s, European filmmakers such as Sergei Eisenstein, F. W. Murnau, and Fritz Lang, along with American innovator D. W. Griffith and the contributions of Charles Chaplin, Buster Keaton and others, continued to advance the medium. In the 1920s, new technology allowed filmmakers to attach to each film a soundtrack of speech, music and sound effects synchronized with the action on the screen. These sound films were initially distinguished by calling them "talking pictures", or talkies.

The next major step in the development of cinema was the introduction of so-called "natural" color. While the addition of sound quickly eclipsed silent film and theater musicians, color was adopted more gradually as methods evolved making it more practical and cost effective to produce "natural color" films. The public was relatively indifferent to color photography as opposed to black-and-white,[citation needed] but as color processes improved and became as affordable as black-and-white film, more and more movies were filmed in color after the end of World War II, as the industry in America came to view color as essential to attracting audiences in its competition with television, which remained a black-and-white medium until the mid-1960s. By the end of the 1960s, color had become the norm for film makers.

Since the decline of the studio system in the 1960s, the succeeding decades saw changes in the production and style of film. New Hollywood, French New Wave and the rise of film school educated independent filmmakers were all part of the changes the medium experienced in the latter half of the 20th century. Digital technology has been the driving force in change throughout the 1990s and into the 21st century.
