Chroma Keying
Chroma key compositing, or chroma keying, is a visual-effects and post-production technique for compositing (layering) two images or video streams together based on colour hues ( chroma range). The technique has been used in many fields to remove a background from the subject of a photo or video – particularly the newscasting, motion picture, and video game industries. A colour range in the foreground footage is made transparent, allowing separately filmed background footage or a static image to be inserted into the scene. The chroma keying technique is commonly used in video production and post-production. This technique is also referred to as colour keying, colour-separation overlay (CSO; primarily by the BBC), or by various terms for specific colour-related variants such as green screen or blue screen; chroma keying can be done with backgrounds of any colour that are uniform and distinct, but green and blue backgrounds are more commonly used because they differ most disti ...

Green Screens Compare With Iman Crosson 20110524
Green is the color between cyan and yellow on the visible spectrum. It is evoked by light which has a dominant wavelength of roughly 495570 nm. In subtractive color systems, used in painting and color printing, it is created by a combination of yellow and cyan; in the RGB color model, used on television and computer screens, it is one of the additive primary colors, along with red and blue, which are mixed in different combinations to create all other colors. By far the largest contributor to green in nature is chlorophyll, the chemical by which plants photosynthesize and convert sunlight into chemical energy. Many creatures have adapted to their green environments by taking on a green hue themselves as camouflage. Several minerals have a green color, including the emerald, which is colored green by its chromium content. During post-classical and early modern Europe, green was the color commonly associated with wealth, merchants, bankers, and the gentry, while red was r ...

Rotoscopy
Rotoscoping is an animation technique that animators use to trace over motion picture footage, frame by frame, to produce realistic action. Originally, animators projected photographed live-action movie images onto a glass panel and traced over the image. This projection equipment is referred to as a rotoscope, developed by Polish-American animator Max Fleischer, and the result is a rotograph. This device was eventually replaced by computers, but the process is still called rotoscoping. In the visual effects industry, ''rotoscoping'' is the technique of manually creating a matte for an element on a live-action plate so it may be composited over another background. Chroma key is more often used for this, as it is faster and requires less work, but rotoscopy provides a higher level of accuracy and is often used in conjunction with chroma-keying. It may also be used if the subject is not in front of a green (or blue) screen, or for practical or economic reasons. Technique Ro ...

RKO Radio Pictures
RKO Radio Pictures Inc., commonly known as RKO Pictures or simply RKO, was an American film production and distribution company, one of the "Big Five" film studios of Hollywood's Golden Age. The business was formed after the Keith-Albee-Orpheum (KAO) theater chain and Joseph P. Kennedy's Film Booking Offices of America (FBO) studio were brought together under the control of the Radio Corporation of America (RCA) in October 1928. RCA chief David Sarnoff engineered the merger to create a market for the company's sound-on-film technology, RCA Photophone, and in early 1929 production began under the RKO name (an abbreviation of Radio-Keith-Orpheum). Two years later, another Kennedy holding, the Pathé studio, was folded into the operation. By the mid-1940s, RKO was controlled by investor Floyd Odlum. RKO has long been renowned for its cycle of musicals starring Fred Astaire and Ginger Rogers in the mid-to-late 1930s. Actors Katharine Hepburn and, later, Robert Mitchum had their ...

Alice Comedies
The ''Alice Comedies'' are a series of animated/live-action shorts created by Walt Disney in the 1920s, in which a live action little girl named Alice (originally played by Virginia Davis) and an animated cat named Julius have adventures in an animated landscape. ''Alice's Wonderland'' Disney, Ub Iwerks, and their staff made the first ''Alice Comedy'', a one-reel (ten-minute) 1923 short subject titled ''Alice's Wonderland'', while still heading the failing Laugh-O-Gram Studio in Kansas City, Missouri. ''Alice's Wonderland'' begins with Alice entering a cartoon studio to witness cartoons being created. Alice is amazed by what she sees: the cartoon characters come to life and play around. After heading to bed that night, she dreams of being in the cartoon world, welcomed by all of the characters. Alice plays with them until a group of lions break free from a cage and chase her. Though never released, this short helped set the stage for what was to come in the later ''Alice Comedi ...

Garbage Matte
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 imag ...

The Great Train Robbery (1903 Film)
''The Great Train Robbery'' is a 1903 American silent film made by Edwin S. Porter for the Edison Manufacturing Company. It follows a gang of outlaws who hold up and rob a steam locomotive at a station in the American West, flee across mountainous terrain, and are finally defeated by a posse of locals. The short film draws on many sources, including a robust existing tradition of Western films, recent European innovations in film technique, the play of the same name by Scott Marble, the popularity of train-themed films, and possibly real-life incidents involving outlaws such as Butch Cassidy. Porter supervised and photographed the film in New York and New Jersey in November 1903; the Edison studio began selling it to vaudeville houses and other venues in the following month. The cast included Justus D. Barnes and G. M. Anderson, who may have also helped with planning and staging. Porter's storytelling approach, though not particularly innovative or unusual for 1903, allowed h ...

Double Exposure
In photography and cinematography, a multiple exposure is the superimposition of two or more exposures to create a single image, and double exposure has a corresponding meaning in respect of two images. The exposure values may or may not be identical to each other. Overview Ordinarily, cameras have a sensitivity to light that is a function of time. For example, a one-second exposure is an exposure in which the camera image is equally responsive to light over the exposure time of one second. The criterion for determining that something is a double exposure is that the sensitivity goes up and then back down. The simplest example of a multiple exposure is a double exposure without flash, i.e. two partial exposures are made and then combined into one complete exposure. Some single exposures, such as "flash and blur" use a combination of electronic flash and ambient exposure. This effect can be approximated by a Dirac delta measure (flash) and a constant finite rectangular window, i ...
