The simplest film recorders typically work by displaying the image on a grayscale cathode ray tube (CRT) placed in front of a photographic camera. In computing, a grayscale or greyscale digital image is an image in which the value of each pixel is a single sample. ... It has been suggested that Crookes tube be merged into this article or section. ... A camera is a device used to capture images, usually photographs, either singly or in sequence such as with video cameras. ...


For color images, the red, green, and blue channels are separately displayed on the same grayscale CRT, and exposed to the same piece of film through a filter of the appropriate color. (This approach yields better resolution and color quality than one could obtain with a color CRT.) The three filters are usually mounted on a motor-driven wheel. The filter wheel, as well as the camera's shutter, aperture, and film motion mechanism are usually controlled by the recorder's electronics and/or the driving software. Color is an important part of the visual arts. ... In photography, a filter is a camera accessory consisting of an optical filter that can be inserted in the optical path. ... In photography, a shutter is a device that administers the exposure by admitting light to the film for a specific period of time. ... a big (1) and a small (2) aperture For other uses, see Aperture (disambiguation). ... Windows XP loading drivers during a Safe Mode bootup A device driver, or a software driver is a specific type of computer software, typically developed to allow interaction with hardware devices. ...


Higher-quality film recorders called LVT (Light Value Transfer) use lasers to write the image directly onto the film, one pixel at a time. This method is better suited to print to large-format media such as poster-size prints. A LASER (from the acronym of Light Amplification by Stimulated Emission of Radiation) is an optical source that emits photons in a coherent beam. ...


In any case, the exposed film is developed and printed by regular photographic chemical processing. Self-developing (Polaroid) film can be used for immediate feedback. The Polaroid Corporation was founded in 1937 by Edwin H. Land. ...

Formats

Film recorders are (or were) available for a variety of film types and formats.The 35mm negative film and transparencies are popular because they can be processed by any photo shop. Single-image 4x5 film and 10x8 is often used for high-quality, large format printing. Simulated 35 mm film with soundtracks _ The outermost strips (on either side) contain the SDDS soundtrack as an image of a digital signal. ... A single slide, showing a color transparency in a plastic frame In photography, a transparency is a still, positive image created on a transparent base using photochemical means. ... // Movie film formats Amateur formats: 8 mm Single-8 Super 8 mm Polavision 9,5 mm film 17. ...


Some models have detachable film holders to handle multiple formats with the same camera. A film holder is a device which holds one or more pieces of photographic film, for insertion into a camera. ...


Uses

Film recorders are used in digital printing to generate master negatives for offset and other bulk printing processes. They are also used to produce the master copies of movies that use computer animation or other special effects based on digital image processing. Digital printing is the reproduction of digital images on physical surface, such as common or photographic paper, film, cloth, plastic, etc. ... Negative lithography stone and positive print of a map of Munich. ... This article or section is in need of attention from an expert on the subject. ... Film is a term that encompasses motion pictures as individual projects, as well as the field in general. ... Computer animation is the art of creating moving images via the use of computers. ... The quality of this article or section may be compromised by peacock terms. You can help Wikipedia by removing peacock terms. ... Digital image processing is the use of computer algorithms to perform image processing on digital images. ...


For preview, archiving, and small-volume reproduction, film recorders have been rendered obsolete by modern printers that produce photographic-quality hardcopies directly on plain paper. This does not cite its references or sources. ...


Film recorders were also commonly used to produce slides for slide projectors; but this need is now largely met by video projectors that project images straight from a computer to a screen. In photography, a transparency is a still, positive image created on a transparent base using photochemical means. ... [carousel slide projector, the most common form of projector] A slide projector is an opto-mechanical device to view photographic slides. ... A video projector takes a video signal and projects the corresponding image on a projection screen using a lens system. ...


Film recorders were among the earliest computer graphics output devices. See, for example: IBM 740 It has been suggested that CG artwork be merged into this article or section. ... The IBM 740 CRT Recorder was announced in 1954 and used with the IBM 701, IBM 704, and IBM 709 computers to draw vector graphics images on 35 mm photographic film (i. ...


Nowadays, film recorders are primarily used in the motion picture film-out process for the ever increasing amount of digital intermediate work being done. Although significant advances in large venue video projection alleviates the need to output to film, there remains a deadlock between the motion picture studios and theater owners over who should pay for the cost of these very costly projection systems. This, combined with the increase in international and independent film production, will keep the demand for film recording steady for at least a decade. To meet Wikipedias quality standards, this article or section may require cleanup. ... Digital intermediate (often abbreviated as DI) describes the process of digitizing a motion picture and manipulating color and other image characteristics to change the look, and is usually the final creative adjustment to a movie before distribution in theaters. ...


Key Manufacturers

Traditional film recorder manufacturers have all but vanished from the scene or have evolved their product lines to cater to the motion picture industry. Arri produces the Arrilaser line of laser-based motion picture film recorders. Celco makes a line of CRT based motion picture film recorders. Lasergraphics is the latest entrant into the cine film recorder market with its twenty year history of dominance in the traditional film recorder business. Lasergraphics this year, 2006, has reintroduced special order production of still film recorders. CCG, formally Agfa film recorders, has been a steady manufacture of film recorders based in Germany. In 2003 Digital Films Systems with Definity introduced the first motion picture film recorder utilizing LCD technology. CCG is an acronym for: collectible card game Combinatory categorial grammar (Computational linguistics), a kind of categorial grammar Canadian Coast Guard Castor Cracking Group Childrens Cancer Study Group Centre for Computational Geography Chesapeake Computer Group, a fleet software company based in Norfolk, VA This page extends a three-character...


Polaroid was a significant producer of film recorders. The top model film recorder that Polaroid produced was the ProPalette 8000 series. Polaroid does not make film recorders any longer. The last LVT machines produced by Kodak / Durst-Dice stopped production in 2002. There are no LVT film recorders currently being produced.

The Record: RVCC's Student Newspaper (744 words)
With the introduction of “Hollywood Renaissance: Film and American Society, 1967-1983,” an honors course in Film Studies, this may no longer be an issue for students who are interested in an academically challenging, yet creatively stimulating semester at RVCC.
Bezanson chose to create a Film Studies course based on the time period of 1967-1983 because “The Hollywood Renaissance in the 1970s was an explosion of creativity in a decade of turmoil,” he said.
However, the features that set this class apart from the other film courses offered at RVCC are that it allows students to challenge their critical thinking skills through an intensive exploration of certain themes/genres, and to elucidate their learning experience through a critical research paper.
