Arriflex D 21 A
Arri Group () (stylized as "ARRI") is a German manufacturer of motion picture film equipment. Based in Munich, the company was founded in 1917. It produces professional motion picture cameras, lenses, lighting and post-production equipment. It is cited by Hermann Simon as an example of a " hidden champion". The Arri Alexa camera system was used to shoot several films that won the Academy Award for Best Cinematography, including '' Hugo'' (2011), ''Life of Pi'' (2012), ''Gravity'' (2013), '' Birdman'' (2014), '' The Revenant'' (2015) and ''1917'' (2019). History Early history Arri was founded in Munich, Germany on 12 September 1917 by August Arnold and Robert Richter as Arnold & Richter Cine Technik. The acronym ''Arri'' was derived from the initial two letters of the founders' surnames, ''Ar''nold and ''Ri''chter. In 1924, Arnold and Richter developed their first film camera, the small and portable Kinarri 35. In 1937, Arri introduced the world's first reflex mirror shutter i ...

Arriflex D-20
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 to the cropping necessary when shooting 35 mm film. In Data m ...

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 1980, 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 optical soundtrack – the gray track on left side of the illustration). These two characteristics are central to the fo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Active Pixel Sensor
An active-pixel sensor (APS) is an image sensor, which was invented by Peter J.W. Noble in 1968, 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), mirrorless interchangeable-lens cameras (MILCs), and lensless imaging for, e.g., blood cells. CMOS sensors emerged as an alternative to charge-coupled device (CCD) image sensors and eventually outsold them by the mid-2000s. The term ''active pixel sensor'' is also used to refer to the individual pixel sensor its ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 negative pulldown, image exposure length on 35 mm for movies ("single-frame" format) is four film perforations, perforations per Film frame, 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 and early 20th centuries, along with various 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 st ...

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, and camcorders 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 elements ...

Arri Alexa
The Arri Alexa is a digital motion picture camera system developed by Arri. The Arri Alexa was introduced in April 2010 and was Arri's first major transition into digital cinematography, after previous efforts including the Arriflex D-20 and D-21. Alexa cameras are designed to be used in feature films, television shows and commercials. Alexa uses the ALEV series of image sensors manufactured by ON Semiconductor. Overview The Alexa camera system introduced their Log-C imaging science as a digital negative, which allows digital cinema images to be processed like scanned film images.

Genesis (Panavision)
The Genesis is a discontinued high-end digital movie camera developed by Panavision, and was available solely by rental. It is based on a proprietary Super 35 1.78:1 (16:9) aspect ratio, 12.4-megapixel, RGB filtered 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''. However, the 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 ''Attack of the Clones''), the Genesis uses a single 12.4 megapixel CCD chip with the same width as a Super 35 mm film frame. The "Panavized" CineAltas did not use Panavision's existing range of 35 mm fil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Film And Video Technology
A film, also known as a movie or motion picture, is a work of visual art that simulates experiences and otherwise communicates ideas, stories, perceptions, emotions, or atmosphere through the use of moving images that are generally, since the 1930s, synchronized with sound and (less commonly) other sensory stimulations. Etymology and alternative terms The name "film" originally referred to the thin layer of photochemical emulsion on the celluloid strip that used to be the actual medium for recording and displaying motion pictures. Many other terms exist for an individual motion-picture, including "picture", "picture show", "moving picture", "photoplay", and "flick". The most common term in the United States is "movie", while in Europe, "film" is preferred. Archaic terms include "animated pictures" and "animated photography". "Flick" is, in general a slang term, first recorded in 1926. It originates in the verb flicker, owing to the flickering appearance of early films. ...
