Miniature effect
Résumé
A miniature effect is a special effect created for motion pictures and television programs using scale models. Scale models are often combined with high speed photography or matte shots to make gravitational and other effects appear convincing to the viewer. The use of miniatures has largely been superseded by in contemporary cinema.
Where a miniature appears in the foreground of a shot, this is often very close to the camera lens — for example when matte-painted backgrounds are used. Since the exposure is set to the object being filmed so the actors appear well-lit, the miniature must be over-lit in order to balance the exposure and eliminate any depth of field differences that would otherwise be visible. This foreground miniature usage is referred to as forced perspective. Another form of miniature effect uses stop motion animation.
The use of scale models in the creation of visual effects by the entertainment industry dates back to the earliest days of cinema. Models and miniatures are copies of people, animals, buildings, settings, and objects. Miniatures or models are used to represent things that do not really exist, or that are too expensive or difficult to film in reality, such as explosions, floods, or fires.
French director Georges Méliès incorporated special effects in his 1902 film Le Voyage dans la Lune (A Trip to the Moon) — including double-exposure, split screens, miniatures and stop-action.
Some of the most influential visual effects films of these early years such as Metropolis (1927), Citizen Kane (1941), Godzilla (1954) The Ten Commandments (1956). The 1933 film King Kong made extensive use of miniature effects including scale models and stop-motion animation of miniature elements.
The use of miniatures in 2001: A Space Odyssey was a major development. In production for three years, the film was a significant advancement in creating convincing models.
In the early 1970s, miniatures were often used to depict disasters in such films as The Poseidon Adventure (1972), Earthquake (1974) and The Towering Inferno (1975).
