Steadicam is a brand of camera stabilizer mount for motion picture cameras that mechanically isolates it from the operator's movement. It allows for a smooth shot, even when moving quickly over an uneven surface. The Steadicam was invented by cameraman Garrett Brown and was introduced in 1975. ==History== Before the camera stabilizing system, a director had two choices for moving (or "tracking") shots: * The camera could be mounted on a camera dolly, a wheeled mount that rolls on tracks or leveled boards. This is time consuming to set up, and depending on the location, impractical in many situations. * The camera operator could hold the camera in his hands. This allows greater speed and flexibility, but even the most skilled operator cannot entirely prevent shaking. Hand-held camera footage has traditionally been considered suitable mostly for documentaries, news, reportage work, live action, unrehearsable footage, or to evoke an atmosphere of authentic immediacy or ''cinéma vérité'' during dramatic sequences. While these cinematic techniques are still common, the Steadicam has added another dimension to motion picture cinematography and videography. A Steadicam essentially combines the stabilized steady footage of a conventional tripod mount with the fluid motion of a dolly shot and the flexibility of hand-held camera work. While smoothly following the operator's broad movements, the Steadicam's armature absorbs jerks, bumps, and shakes. The Steadicam was introduced to the industry in 1975 by inventor and cameraman Garrett Brown,〔http://www.steadicam.com/index.html〕 who originally named the invention the "Brown Stabilizer". After completing the first working prototype, Brown shot a ten-minute demo reel of the revolutionary moves this new device could produce. This reel was seen by numerous directors, including Stanley Kubrick and John G. Avildsen. The Steadicam was subsequently licensed to and manufactured by Cinema Products Corporation, which later diversified the brand into a consumer line for DV cameras. The Steadicam was first used in the Best Picture–nominated Woody Guthrie biopic ''Bound for Glory'' (1976), debuting with a shot that compounded the Steadicam's innovation: cinematographer Haskell Wexler had Brown start the shot on a fully elevated platform crane which jibbed down, and when it reached the ground, Brown stepped off and walked the camera through the set. This technically audacious and previously impossible shot created considerable interest in how it had been accomplished, and impressed the Academy enough for Wexler to win the Oscar for Best Cinematography that year. It was then used in extensive running and chase scenes on the streets of New York City in ''Marathon Man'' (1976), which was actually released two months before ''Bound for Glory''. It landed a notable third credit in Avildsen's Best Picture–winning ''Rocky'' (1976), where it was an integral part of the film's Philadelphia street jogging/training sequences and the run up the Art Museum's flight of stairs, as well as the fight scenes (where it can even be plainly seen in operation at the ringside during some wide shots of the final fight). ''Rocky'' was also released before ''Bound For Glory''. Garrett Brown was the Steadicam operator on all of these.〔 ''The Shining'' (1980) pushed Brown's innovations even further, when director Stanley Kubrick requested that the camera shoot from barely above the floor. This prompted the innovation of a "low mode" bracket to mount the top of a camera to the bottom of an inverted post, which substantially increased the creative angles of the system, which previously could not go much lower than the operator's waist height.〔Serena Ferrara (2000). ''Steadicam: Techniques and Aesthetics''. Oxford: Focal Press. pp. 26–31.〕 This low-mode concept remains the most important extension to the system since its inception. A Steadicam rig was also employed during the filming of ''Return of the Jedi'' (1983), in conjunction with two gyroscopes for extra stabilization, to film the background plates for the speeder bike chase. Brown walked through a redwood forest, with the camera running at a speed of one frame per second. The end result, when projected at 24 frames per second, gave the impression of flying through the air at perilous speeds.〔Brown, Garrett. "Return of the Jedi", ''American Cinematographer'', June 1983.〕 In the Michael Crichton film ''Runaway'' (1984), a Steadicam rig was used to simulate the point of view of a futuristic smart bullet in flight while targeting specific individuals by their heat signature. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「steadicam」の詳細全文を読む スポンサード リンク
