Motion Control Photography
Motion control photography is a technique used in Photograph, still and motion photography that enables precise control of, and optionally also allows repetition of, camera movements. It can be used to facilitate special effects photography. The process can involve filming several elements using the same camera motion, and then compositing the elements into a single image. Other effects are often used along with motion control, such as chroma key to aid the compositing. Motion control camera rigs are also used in still photography with or without compositing; for example in Long-exposure photography, long exposures of moving vehicles. Today's computer technology allows the programmed camera movement to be processed, such as having the move scaled up or down for different sized elements. Common applications of this process include shooting with Miniature effect, miniatures, either to composite several miniatures or to composite miniatures with full-scale elements. The process is ...

Analog Computer
An analog computer or analogue computer is a type of computer that uses the continuous variation aspect of physical phenomena such as electrical, mechanical, or hydraulic quantities (''analog signals'') to model the problem being solved. In contrast, digital computers represent varying quantities symbolically and by discrete values of both time and amplitude (digital signals). Analog computers can have a very wide range of complexity. Slide rules and nomograms are the simplest, while naval gunfire control computers and large hybrid digital/analog computers were among the most complicated. Complex mechanisms for process control and protective relays used analog computation to perform control and protective functions. Analog computers were widely used in scientific and industrial applications even after the advent of digital computers, because at the time they were typically much faster, but they started to become obsolete as early as the 1950s and 1960s, although they rem ...

Motion Capture
Motion capture (sometimes referred as mo-cap or mocap, for short) is the process of recording the movement of objects or people. It is used in military, entertainment, sports, medical applications, and for validation of computer vision and robots. In filmmaking and video game development, it refers to recording actions of human actors, and using that information to animate digital character models in 2-D or 3-D computer animation.Andrew Harris Salomon, Feb. 22, 2013, Backstage MagazineGrowth In Performance Capture Helping Gaming Actors Weather Slump Accessed June 21, 2014, "..But developments in motion-capture technology, as well as new gaming consoles expected from Sony and Microsoft within the year, indicate that this niche continues to be a growth area for actors.

Match Moving
In visual effects, match moving is a technique that allows the insertion of computer graphics into live-action footage with correct position, scale, orientation, and motion relative to the photographed objects in the shot. The term is used loosely to describe several different methods of extracting camera motion information from a motion picture. Sometimes referred to as motion tracking or camera solving, match moving is related to rotoscoping and photogrammetry. Match moving is sometimes confused with motion capture, which records the motion of objects, often human actors, rather than the camera. Typically, motion capture requires special cameras and sensors and a controlled environment (although recent developments such as the Kinect camera and Apple's Face ID have begun to change this). Match moving is also distinct from motion control photography, which uses mechanical hardware to execute multiple identical camera moves. Match moving, by contrast, is typically a softwa ...

Dykstraflex
The Dykstraflex was the first digital motion control photography camera system, named after its primary developer John Dykstra. Numerous people actually created the camera, with the critical electronics being created by Alvah J. Miller and Jerry Jeffress. The camera was developed in 1976 specifically for complex special effects shots in '' Star Wars''. Using old VistaVision cameras (for their high image resolution), created by engineers at Paramount Pictures in 1954, and hand wire wrapped TTL chips, the all-digitally controlled system allowed for 7 axes of motion: roll, pan, tilt, swing, boom, traverse, track, lens focus, motor drive, shutter control, and their duplication in multiple takes. Dykstra's development of this first digital motion control camera system earned himself, Al Miller, and Jerry Jeffress Academy Awards The Academy Awards, better known as the Oscars, are awards for artistic and technical merit for the American and international film industry.

Slit-scan
The slit-scan photography technique is a photographic and cinematographic process where a moveable slide, into which a slit has been cut, is inserted between the camera and the subject to be photographed. More generally, "slit-scan photography" refers to cameras that use a slit, which is particularly used in scanning cameras in panoramic photography. This has numerous applications. This article discusses the manual artistic technique.{{cite web, url=https://petapixel.com/2017/10/18/role-slit-scan-image-science-art/, title=The Role of the Slit-Scan Image in Science and Art, date=18 October 2017, website=petapixel.com Use in cinematography Originally used in static photography to achieve blurriness or deformity, the slit-scan technique was perfected for the creation of spectacular animations. It enables the cinematographer to create a psychedelic flow of colors. Though this type of effect is now often created through computer animation, slit-scan is a mechanical technique. J ...

A Space Odyssey (film)
''2001: A Space Odyssey'' is a 1968 science fiction novel written by Arthur C. Clarke and the 1968 film directed by Stanley Kubrick. It is a part of Clarke's ''Space Odyssey'' series, the first of four novels and two films. Both the novel and the film are partially based on Clarke's 1948 short story " The Sentinel", an entry in a BBC short story competition, and "Encounter in the Dawn", published in 1953 in the magazine ''Amazing Stories''. Resources After deciding on Clarke's 1948 short story "The Sentinel" as the starting point, and with the themes of man's relationship with the universe in mind, Clarke sold Kubrick five more of his stories to use as background materials for the film. These included "Breaking Strain", "Out of the Cradle, Endlessly Orbiting...", "Who's There?", " Into the Comet", and " Before Eden". Additionally, important elements from two more Clarke stories, "Encounter in the Dawn" and (to a somewhat lesser extent) "Rescue Party", made their way in ...

James Whitney (filmmaker)
James Whitney (December 27, 1921 – April 8, 1982), younger brother of John, was a filmmaker regarded as one of the great masters of abstract cinema. Several of his films are classics in the genre of visual music. Early life James Whitney was born December 27, 1921, in Pasadena, California, and lived all his life in the Los Angeles area. He studied painting, and traveled in England before the outbreak of World War II. In 1940, he returned to Pasadena. Career – early works James completed a number of short films over four decades, two of which required at least five years of work. James collaborated with his brother John for some of his early film work. The first of the brothers' films was '' Twenty-Four Variations on an Original Theme''. Its structure was influenced by Schoenberg's serial principles. James spent 3 years working on '' Variations on a Circle'' (1942), which lasts some 20 minutes, and was made with 8mm film. James and John created their series of Five ' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Servomechanism
In control engineering a servomechanism, usually shortened to servo, is an automatic device that uses error-sensing negative feedback to correct the action of a mechanism. On displacement-controlled applications, it usually includes a built-in encoder or other position feedback mechanism to ensure the output is achieving the desired effect. The term correctly applies only to systems where the feedback or error-correction signals help control mechanical position, speed, attitude or any other measurable variables. For example, an automotive power window control is not a servomechanism, as there is no automatic feedback that controls position—the operator does this by observation. By contrast a car's cruise control uses closed-loop feedback, which classifies it as a servomechanism. Applications Position control A common type of servo provides ''position control''. Commonly, servos are electric, hydraulic, or pneumatic. They operate on the principle of negative feedback ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
