Arriflex D-20
{{short description, American digital motion picture camera The Arriflex D-20 is a film-style digital motion picture camera made by Arri first introduced in November 2005. The camera's attributes are its optical viewfinder, modularity, and 35mm-width CMOS sensor. The camera was discontinued in 2008 when its successor, the Arriflex D-21, was introduced. Overview The D-20 uses a single CMOS sensor the width of a Super 35 film gate aperture. Effectively the D-20, when used with current 35 mm PL mount motion picture lenses, yields the same field of view and depth of field as Super 35 mm film motion picture cameras. The D-20 captures images in two main modes: *In Data mode the sensor uses 2880x2160 active pixels generating RAW Bayer-data at 12 bit in a 4:3 aspect ratio. The RAW data then needs to be processed outboard to generate a full color image. A delivery aspect ratio for theatrical release, commonly 1.85:1, is achieved by cropping from the original image, similar ...

Super 35
Super 35 (originally known as Superscope 235) is a motion picture film format that uses exactly the same film stock as standard 35 mm film, but puts a larger image frame on that stock by using the space normally reserved for the optical analog sound track. History Super 35 was revived from a similar Superscope variant known as Superscope 235, which was originally developed by the Tushinsky Brothers (who founded Superscope Inc. in 1954) for RKO in 1954. The first film to be shot in Superscope was '' Vera Cruz'', a western film produced by Hecht-Lancaster Productions and distributed through United Artists. When cameraman Joe Dunton was preparing to shoot ''Dance Craze'' in 1982, he chose to revive the Superscope format by using a full silent-standard gate and slightly optically recentering the lens port (to adjust for the inclusion of the area of the optic soundtrack -the gray track on left side of the illustration). These two characteristics are central to the format. It ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Active Pixel Sensor
An active-pixel sensor (APS) is an image sensor where each pixel sensor unit cell has a photodetector (typically a pinned photodiode) and one or more active transistors. In a metal–oxide–semiconductor (MOS) active-pixel sensor, MOS field-effect transistors (MOSFETs) are used as amplifiers. There are different types of APS, including the early NMOS APS and the now much more common complementary MOS (CMOS) APS, also known as the CMOS sensor. CMOS sensors are used in digital camera technologies such as cell phone cameras, web cameras, most modern digital pocket cameras, most digital single-lens reflex cameras (DSLRs), and mirrorless interchangeable-lens cameras (MILCs). CMOS sensors emerged as an alternative to charge-coupled device (CCD) image sensors and eventually outsold them by the mid-2000s decade. The term ''active pixel sensor'' is also used to refer to the individual pixel sensor itself, as opposed to the image sensor. In this case, the image sensor is sometimes c ...

35mm Movie Film
35 mm film is a film gauge used in filmmaking, and the film standard. In motion pictures that record on film, 35 mm is the most commonly used gauge. The name of the gauge is not a direct measurement, and refers to the nominal width of the 35 mm format photographic film, which consists of strips wide. The standard image exposure length on 35 mm for movies ("single-frame" format) is four perforations per frame along both edges, which results in 16 frames per foot of film. A variety of largely proprietary gauges were devised for the numerous camera and projection systems being developed independently in the late 19th century and early 20th century, as well as a variety of film feeding systems. This resulted in cameras, projectors, and other equipment having to be calibrated to each gauge. The 35 mm width, originally specified as inches, was introduced around 1890 by William Kennedy Dickson and Thomas Edison, using 120 film stock supplied by George Eastman. ...

Bayer Mask
A Bayer filter mosaic is a color filter array (CFA) for arranging RGB color filters on a square grid of photosensors. Its particular arrangement of color filters is used in most single-chip digital image sensors used in digital cameras, camcorders, and scanners to create a color image. The filter pattern is half green, one quarter red and one quarter blue, hence is also called BGGR, RGBG, GRBG, or RGGB. It is named after its inventor, Bryce Bayer of Eastman Kodak. Bayer is also known for his recursively defined matrix used in ordered dithering. Alternatives to the Bayer filter include both various modifications of colors and arrangement and completely different technologies, such as color co-site sampling, the Foveon X3 sensor, the dichroic mirrors or a transparent diffractive-filter array. Explanation Bryce Bayer's patent (U.S. Patent No. 3,971,065) in 1976 called the green photosensors ''luminance-sensitive elements'' and the red and blue ones ''chrominance-sensitive ...

Genesis (Panavision)
The Genesis is a discontinued high-end Digital data, digital movie camera developed by Panavision, and was available solely by rental. It is based on a Property, proprietary Super 35 1.78:1 (16:9) aspect ratio (image), aspect ratio, 12.4-megapixel, RGB filtered Charge-coupled device, CCD sensor. It was first used by a feature crew to shoot Bryan Singer's ''Superman Returns,'' and was shortly followed up thereafter by the World War I film ''Flyboys (film), Flyboys''. However, the Visual effects, computer effect-heavy nature of these two movies meant that ultimately the comedy ''Scary Movie 4'' was the first theatrically released feature primarily shot with the Genesis. It was discontinued in 2012 and succeeded by the Millennium DXL line developed with Red Digital Cinema. Background Unlike the 2/3" 3-CCD imaging system used in Sony's HDW-F900 CineAlta camera (used in ''Star Wars: Episode II – Attack of the Clones, Attack of the Clones''), the Genesis uses a single 12.4 megapixel ...

As a self-described "camera fanatic" owning over 1,000 models, Jannard started the company with the intent to deliver a (relatively) affordable 4K digital cinema camera. Jannard dates this idea to a time when he bought a Sony HDR-FX1 video camera and learned that the files had to be converted with software from Lumiere HD and were not viewable on Mac OS. Lumiere HD's owner Frederic Lumiere collaborated with Jannard on developing an alternative and intr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Film And Video Technology
A film also called a movie, motion picture, moving picture, picture, photoplay or (slang) flick is a work of visual art that simulates experiences and otherwise communicates ideas, stories, perceptions, feelings, beauty, or atmosphere through the use of moving images. These images are generally accompanied by sound and, more rarely, other sensory stimulations. The word "cinema", short for cinematography, is often used to refer to filmmaking and the film industry, and to the art form that is the result of it. Recording and transmission of film The moving images of a film are created by photographing actual scenes with a motion-picture camera, by photographing drawings or miniature models using traditional animation techniques, by means of CGI and computer animation, or by a combination of some or all of these techniques, and other visual effects. Before the introduction of digital production, series of still images were recorded on a strip of chemically sensitize ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
