Rostrum Camera
A rostrum camera is a specially designed camera used in television production and filmmaking to animate a still picture or object. It consists of a moving lower platform on which the article to be filmed is placed, while the camera is placed above on a column. Many visual effects can be created from this simple setup, although it is most often used to add interest to static objects. The camera can, for example, traverse across a painting, and using wipes and zooms, change a still picture into a sequence suitable for television or movie productions. The controls of the camera differ considerably from those of a regular motion picture camera. The key to its operation is one or more frame counters. These enable the camera operator to roll the film backwards and forwards through the film gate, and to know exactly which frame is being exposed at a given time. Also key is the way the operation of the shutter is completely independent from the film transport, so a given frame may be expos ...

Movie Camera
A movie camera (also known as a film camera and cine-camera) is a type of photographic camera that rapidly takes a sequence of photographs, either on an image sensor or onto film stock, in order to produce a moving image to project onto a movie screen. In contrast to the still camera, which captures a single image at a time, by way of an intermittent mechanism, the movie camera takes a series of images; each image is a ''frame'' of film. The strips of frames are projected through a movie projector at a specific frame rate (number of frames per second) to show a moving picture. When projected at a given frame rate, the persistence of vision allows the eyes and brain of the viewer to merge the separate frames into a continuous moving picture. History An interesting forerunner to the movie camera was the machine invented by Francis Ronalds at the Kew Observatory in 1845. A photosensitive surface was drawn slowly past the aperture diaphragm of the camera by a clockwork mechanism ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Television Program
Television, sometimes shortened to TV, is a telecommunication medium for transmitting moving images and sound. The term can refer to a television set, or the medium of television transmission. Television is a mass medium for advertising, entertainment, news, and sports. Television became available in crude experimental forms in the late 1920s, but only after several years of further development was the new technology marketed to consumers. After World War II, an improved form of black-and-white television broadcasting became popular in the United Kingdom and the United States, and television sets became commonplace in homes, businesses, and institutions. During the 1950s, television was the primary medium for influencing public opinion.Diggs-Brown, Barbara (2011''Strategic Public Relations: Audience Focused Practice''p. 48 In the mid-1960s, color broadcasting was introduced in the U.S. and most other developed countries. The availability of various types of archival stora ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Filmmaking
Filmmaking (film production) is the process by which a motion picture is produced. Filmmaking involves a number of complex and discrete stages, starting with an initial story, idea, or commission. It then continues through screenwriting, casting, pre-production, shooting, sound recording, post-production, and screening the finished product before an audience that may result in a film release and an exhibition. Filmmaking occurs in a variety of economic, social, and political contexts around the world. It uses a variety of technologies and cinematic techniques. Although filmmaking originally involved the use of film, most film productions are now digital. Today, filmmaking refers to the process of crafting an audio-visual story commercially for distribution or broadcast. Production stages Film production consists of five major stages: * Development: Ideas for the film are created, rights to existing intellectual properties are purchased, etc., and the screenplay is writte ...

Exposure (photography)
In photography, exposure is the amount of light per unit area (the image plane's illuminance times the exposure time) reaching a frame of photographic film or the surface of an electronic image sensor, as determined by shutter speed, lens F-number, and scene luminance. Exposure is measured in lux seconds, and can be computed from exposure value (EV) and scene luminance in a specified region. An "exposure" is a single shutter cycle. For example, a long exposure refers to a single, long shutter cycle to gather enough dim light, whereas a multiple exposure involves a series of shutter cycles, effectively layering a series of photographs in one image. The accumulated ''photometric exposure'' (''H''v) is the same so long as the total exposure time is the same. Definitions Radiant exposure Radiant exposure of a ''surface'', denoted ''H''e ("e" for "energetic", to avoid confusion with photometric quantities) and measured in , is given by :H_\mathrm = E_\mathrmt, where *''E ...

Matte (filmmaking)
Mattes are used in photography and special effects filmmaking to combine two or more image elements into a single, final image. Usually, mattes are used to combine a foreground image (e.g. actors on a set) with a background image (e.g. a scenic vista or a starfield with planets). In this case, the matte is the background painting. In film and stage, mattes can be physically huge sections of painted canvas, portraying large scenic expanses of landscapes. In film, the principle of a matte requires masking certain areas of the film emulsion to selectively control which areas are exposed. However, many complex special-effects scenes have included dozens of discrete image elements, requiring very complex use of mattes and layering mattes on top of one another. For an example of a simple matte, the director may wish to depict a group of actors in front of a store, with a massive city and sky visible above the store's roof. There would be two images—the actors on the set, and the ima ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superimposition
Superimposition is the placement of one thing over another, typically so that both are still evident. Graphics In graphics, superimposition is the placement of an image or video on top of an already-existing image or video, usually to add to the overall image effect, but also sometimes to conceal something (such as when a different face is superimposed over the original face in a photograph). Cartography This technique is used in cartography to produce photomaps by superimposing grid lines, contour lines and other linear or textual mapping features over aerial photographs. 2D images Superimposition of two-dimensional images containing correlated periodic grid structures may produce moiré patterns. Superimposition of two correlated layers comprising parallel lines or curves may give rise line moiré patterns. The movement of one of the layers results in a faster movement of the line moiré superimposition image. Such optical acceleration is known as moiré speedup (check fo ...

Ken Morse
Ken Morse (born c. 1944) is a British rostrum camera operator who has provided visual effects to BBC television programmes over several decades. Ken Morse worked as a cinema projectionist from the age of 12 for about 10 years. Morse joined the film industry in the 1960s, working originally in stop motion animation before moving to the rostrum camera. The British Academy ( BAFTA) presented him with a Lifetime Achievement award to recognise his contributions to the industry over nearly forty years. He is based in Shepherd's Bush, London, England. Morse has been mentioned in several British sketch shows: ''The Fast Show'' listed his name in a spoof set of credits; and ''Big Train'' included a sketch about a rostrum cameraman driven mad by always being overshadowed by Ken Morse. The one-off comedy special '' Clinton: His Struggle with Dirt'' (produced by Armando Iannucci) credited 'Rostrum Camera' to "Not Ken Morse". He was also credited for 'Rostrum Camera' in the spoof credits fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Closing Credits
Closing credits or end credits are a list of the cast and crew of a particular motion picture, television program, or video game. Where opening credits appear at the beginning of a work, closing credits appear close to, or at the very end of a work. A full set of credits can include the cast and crew, but also production sponsors, distribution companies, works of music licensed or written for the work, various legal disclaimers, such as copyright and more. Typically, the closing credits appear in white lettering on a solid black background, often with a musical background. Credits are either a series of static frames, or a single list that scrolls from the bottom of the screen to the top. Occasionally closing credits will divert from this standard form to scroll in another direction, include illustrations, extra scenes, bloopers, joke credits, or post-credits scenes. The use of closing credits in film to list complete production crew and the cast was not firmly established i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ken Burns Effect
The Ken Burns effect is a type of panning and zooming effect used in film and video production from still imagery. The name derives from extensive use of the technique by American documentarian Ken Burns. This technique had also been used to produce animatics, simple animated mockups used to previsualize motion pictures, but Burns's name has become associated with the effect in much the same way as Alfred Hitchcock is associated with the dolly zoom. The feature enables a widely used technique of embedding still photographs in motion pictures, displayed with slow zooming and panning effects, and fading transitions between frames. Usage The technique is principally used when film or video material is not available. Action is given to still photographs by slowly zooming in on subjects of interest and panning from one subject to another. For example, in a photograph of a baseball team, one might slowly pan across the faces of the players and come to a rest on the player the narr ...

Animation Camera
An animation camera, a type of rostrum camera, is a movie camera specially adapted for frame-by-frame shooting of animation. It consists of a camera body with lens and film magazines, and is most often placed on a stand that allows the camera to be raised and lowered above a table often having both top and underneath lighting. The artwork to be photographed is placed on this table. For stop motion photography, the camera can also be mounted on a tripod or other support, pointing in any desired direction. Since most animation is now produced digitally, new animation cameras are not widely manufactured. Image scanners, video cameras and digital SLRs have taken their place. Examples of professional animation cameras (16 and 35 mm) A partial list of manufacturers of animation cameras includes: * Acme Tool and Manufacturing (USA) * Crass (Germany) * Neilson-Hordell (UK) * Oxberry (USA) * Double M Industries (USA) * A.I.A. Productions (USA) * Mechanical Concepts (USA) The B ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Animation Stand
An animation stand is a device assembled for the filming of any kind of animation that is placed on a flat surface, including cel animation, graphic animation, clay animation, and silhouette animation. Traditionally, the flat surface that the animation rests on is some kind of table that the animator sits at. Pegs made specifically for animation are embedded into the table, in at least two slots allowing the pegs to slide from side to side, permitting horizontal movement of images, but can also be easily fixed into position for the accurate positioning ("registration") of the artwork. Opposite the animator is a series of supporting arms and supports, on top of which is mounted a film or video camera, pointing down toward the artwork, which films the artwork, frame-by-frame, as it is slowly moved and changed by the operator. The vertical positioning of the animation camera, always shooting down, is the main component that defines an animation stand, as opposed to a stop motion ...
