Pathécolor
Pathécolor, later renamed Pathéchrome, was an early mechanical stencil-based film tinting process for movies developed by Segundo de Chomón for Pathé in the early 20th century. Among the last feature films to use this process were the British revue film ''Elstree Calling'' (1930) and the Mexican film ''Robinson Crusoe'' (1954) by Spanish Surrealist Luis Buñuel. The Pathécolor stencil process should not be confused with the later Pathécolor, Pathé Color and Color by Pathé trade names seen in screen credits and advertising materials. Like Metrocolor, WarnerColor and Color by DeLuxe, these were simply rebrandings, for advertising purposes, of the use of Eastman Kodak's Eastmancolor color negative film for the original photography. However, the stencil process was not a color photography process and did not use color film. Like computer-based film colorization processes, it was a way of arbitrarily adding selected colors to films originally photographed and printed in black-and ...

List Of Early Color Feature Films
This is a list of early feature-length color films (including primarily black-and-white films that have one or more color sequences) made up to about 1936, when the Technicolor three-strip process firmly established itself as the major-studio favorite. About a third of the films are thought to be lost films, with no prints surviving. Some have survived incompletely or only in black-and-white copies made for TV broadcast use in the 1950s. Background The earliest attempts to produce color films involved either tinting the film broadly with washes or baths of dyes, or pains-takingly hand-painting certain areas of each frame of the film with transparent dyes. Stencil-based techniques such as Pathéchrome were a labor-saving alternative if many copies of a film had to be colored: each dye was rolled over the whole print using an appropriate stencil to restrict the dye to selected areas of each frame. The Handschiegl color process was a comparable technique. Because transparent dyes ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Film Colorization
Film colorization (American English; or colourisation [British English], or colourization [Canadian English and Oxford English]) is any process that adds color to black-and-white, sepia, or other monochrome moving-picture images. It may be done as a special effect, to "modernize" black-and-white films, or to restore color films. The first examples date from the early 20th century, but colorization has become common with the advent of digital image processing. Early techniques Hand colorization The first film colorization methods were hand done by individuals. For example, at least 4% of George Méliès' output, including some prints of ''A Trip to the Moon'' from 1902 and other major films such as ''The Kingdom of the Fairies'', '' The Impossible Voyage'', and ''The Barber of Seville'' were individually hand-colored by Elisabeth Thuillier's coloring lab in Paris. Thuillier, a former colorist of glass and celluloid products, directed a studio of two hundred peo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Color Film Systems
This is a list of color film processes known to have been created for photographing and exhibiting motion pictures in color since the first attempts were made in the late 1890s. It is limited to "natural color" processes, meaning processes in which the color is photographically recorded and reproduced rather than artificially added by hand-painting, stencil coloring, or other arbitrary " colorization" methods. Legend *Process: the name of the process, as advertised by the company if commercialized. Known alternative names and second-party commercial aliases are also shown. *Year: The earliest known year of existence based on patents, reports of demonstrations, etc. The first public showing or commercial use (if any) may be later. *Projection method: a classification into one of four process types, plus a notation of how many primary colors were used:Additive: multiple black-and-white images photographed through color filters are projected through corresponding filters and united on ...

Elstree Calling
''Elstree Calling'' is a 1930 British comedy musical film directed by Adrian Brunel and Alfred Hitchcock at Elstree Studios. Synopsis The film, referred to as "A Cine-Radio Revue" in its original publicity, is a lavish musical film revue and was Britain's answer to the Hollywood revues which had been produced by the major studios in the United States, such as ''Paramount on Parade'' (1930) and ''The Hollywood Revue of 1929''. The revue has a slim plot about its being a television broadcast. The film consists of 19 comedy and music vignettes linked by running jokes of an aspiring Shakespearean actor and technical problems with a viewer's TV set. Production background Among Hitchcock's contributions was the comic linking segments about a man trying to "tune in" the revue on his television set, but always failing to get the picture for long because of his needless tinkering. In the UK, John Logie Baird's work in mechanical television in the 1920s made television a topical subject a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Release Print
A release print is a copy of a film that is provided to a movie theater for exhibition. Definitions Release prints are not to be confused with other types of prints used in the photochemical post-production process: * Rush prints, or dailies, are one-light, contact-printed copies made from an unedited roll of original camera negative immediately after processing and screened to the cast and crew in order to ensure that the takes can be used in the final film. * Workprints, sometimes called cutting copies, are, like rush prints, copies of a camera negative roll, or from selected takes. A workprint may be roughly corrected for brightness and color balance. The prints are used for editing before the negative itself is conformed, or cut to match the edited workprint. * An answer print is made either from the cut camera negative or an interpositive, depending on the production workflow, in order to verify that the grading ("timing" in American English) conforms to specifications, ...

List Of Film Formats
This list of motion picture film formats catalogues formats developed for shooting or viewing motion pictures, ranging from the Chronophotographe format from 1888, to mid-20th century Film format, formats such as the 1953 CinemaScope format, to more recent formats such as the 1992 IMAX HD format. To be included in this list, the formats must all have been used in the field or for test shooting, and they must all use photochemical images that are formed or projected on a film base, a transparent substrate which supports the photosensitive emulsion. As well, the formats must have been used to make more than just a few test frames. The camera must be fast enough (in frames per second) to create an illusion of motion consistent with the persistence of vision phenomenon. The format must be significantly unique from other listed formats in regard to its image capture or movie projector, image projection. The format characteristics should be clearly definable in several listed parameter ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pantograph
A pantograph (, from their original use for copying writing) is a mechanical linkage connected in a manner based on parallelograms so that the movement of one pen, in tracing an image, produces identical movements in a second pen. If a line drawing is traced by the first point, an identical, enlarged, or miniaturized copy will be drawn by a pen fixed to the other. Using the same principle, different kinds of pantographs are used for other forms of duplication in areas such as sculpting, minting, engraving, and milling. Because of the shape of the original device, a pantograph also refers to a kind of structure that can compress or extend like an accordion, forming a characteristic rhomboidal pattern. This can be found in extension arms for wall-mounted mirrors, temporary fences, pantographic knives, scissor lifts, and other scissor mechanisms such as the pantograph used on electric locomotives and trams. History The ancient Greek engineer Hero of Alexandria described pant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stylus
A stylus (plural styli or styluses) is a writing utensil or a small tool for some other form of marking or shaping, for example, in pottery. It can also be a computer accessory that is used to assist in navigating or providing more precision when using touchscreens. It usually refers to a narrow elongated staff, similar to a modern ballpoint pen. Many styluses are heavily curved to be held more easily. Another widely used writing tool is the stylus used by blind users in conjunction with the slate for punching out the dots in Braille. Etymology The English word ''stylus'' has two plurals: ''styli'' and ''styluses''. The original Latin word was spelled ; the spelling ''stylus'' arose from an erroneous connection with Greek (), 'pillar'.''Oxford Latin Dictionary'', s.v. "stilus" (2012). The Latin word had several meanings, including "a long, sharply pointed piece of metal; the stem of a plant; a pointed instrument for incising letters; the stylus (as used in literary composi ...

Rotoscoping
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 ...

Frosted Glass
Frosted glass is produced by the sandblasting or acid etching of clear sheet glass. This creates a pitted surface on one side of the glass pane and has the effect of rendering the glass translucent by scattering the light which passes through, thus blurring images while still transmitting light. It has 10-20% Opacity. Applications: * To achieve visual privacy while still allowing light to pass through. * Decorative patterns may be created on plain glass by using wax or other inhibitors to retain transparent areas. * To distribute light uniformly in a photographic contact printer. * To create an airtight seal in tubes. The frosted glass effect can also be achieved by the application of vinyl film, used as a sort of stencil on the glass surface. "Photo-resist", or photo-resistant film is also available, which can be produced to mask off the area surrounding a decorative design, or logo on the glass surface. A similar effect may also be accomplished with the use of canned fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Film Frame
In filmmaking, video production, animation, and related fields, a frame is one of the many ''still images'' which compose the complete ''moving picture''. The term is derived from the historical development of film stock, in which the sequentially recorded single images look like a framed picture when examined individually. The term may also be used more generally as a noun or verb to refer to the edges of the image as seen in a camera viewfinder or projected on a screen. Thus, the camera operator can be said to keep a car in frame by panning with it as it speeds past. Overview When the moving picture is displayed, each frame is flashed on a screen for a short time (nowadays, usually 1/24, 1/25 or 1/30 of a second) and then immediately replaced by the next one. Persistence of vision blends the frames together, producing the illusion of a moving image. The frame is also sometimes used as a unit of time, so that a momentary event might be said to last six frames, the actual dur ...

Black-and-white
Black-and-white (B&W or B/W) images combine black and white in a continuous spectrum, producing a range of shades of grey. Media The history of various visual media began with black and white, and as technology improved, altered to color. However, there are exceptions to this rule, including black-and-white fine art photography, as well as many film motion pictures and art film(s). Photography Contemporary use Since the late 1960s, few mainstream films have been shot in black-and-white. The reasons are frequently commercial, as it is difficult to sell a film for television broadcasting if the film is not in color. 1961 was the last year in which the majority of Hollywood films were released in black and white. Computing In computing terminology, ''black-and-white'' is sometimes used to refer to a binary image consisting solely of pure black pixels and pure white ones; what would normally be called a black-and-white image, that is, an image containing shades of ...
