4 Perf
Negative pulldown is the manner in which an image is exposed on a film stock, described in the number of film perforations spanned by an individual frame. It can also describe the orientation of the image on the negative, whether it is captured horizontally or vertically. Changing the number of exposed perforations allows a cinematographer to change both the aspect ratio of the image and the size of the area on the film stock that the image occupies (which affects image clarity). The most common negative pulldowns for 35 mm film are 4-perf and 3-perf, the latter of which is usually used in conjunction with Super 35. 2-perf, used in Techniscope in the 1960s, is enjoying a slight resurgence due to the birth of digital intermediate techniques eliminating the need for optical lab work. Vertical pulldown is overwhelmingly the dominant axis of motion in cinematography, although horizontal pulldown is used in IMAX, VistaVision (still in use for some visual effects work), and in 3 ...

4 Perf 3 Perf And 2 Perf 35 Mm Film Compared
4 (four) is a number, numeral and digit. It is the natural number following 3 and preceding 5. It is the smallest semiprime and composite number, and is considered unlucky in many East Asian cultures. In mathematics Four is the smallest composite number, its proper divisors being and . Four is the sum and product of two with itself: 2 + 2 = 4 = 2 x 2, the only number b such that a + a = b = a x a, which also makes four the smallest squared prime number p^. In Knuth's up-arrow notation, , and so forth, for any number of up arrows. By consequence, four is the only square one more than a prime number, specifically three. The sum of the first four prime numbers two + three + five + seven is the only sum of four consecutive prime numbers that yields an odd prime number, seventeen, which is the fourth super-prime. Four lies between the first proper pair of twin primes, three and five, which are the first two Fermat primes, like seventeen, which is the third. On the other hand, t ...

Aspect Ratio (image)
The aspect ratio of an image is the ratio of its width to its height, and is expressed with two numbers separated by a colon, such as ''16:9'', sixteen-to-nine. For the ''x'':''y'' aspect ratio, the image is ''x'' units wide and ''y'' units high. Common aspect ratios are 1.85:1 and 2.39:1 in cinematography, 4:3 and 16:9 in television photography, and 3:2 in still photography. Some common examples The common film aspect ratios used in cinemas are 1.85:1 and 2.39:1.The 2.39:1 ratio is commonly labeled 2.40:1, e.g., in the American Society of Cinematographers' ''American Cinematographer Manual'' (Many widescreen films before the 1970 SMPTE revision used 2.35:1). Two common videographic aspect ratios are 4:3 (1.:1), the universal video format of the 20th century, and 16:9 (1.:1), universal for high-definition television and European digital television. Other cinema and video aspect ratios exist, but are used infrequently. In still camera photography, the most common aspect ra ...

Aaton
Aaton Digital (formerly known as Aaton) is a French motion picture equipment manufacturer, based in Grenoble, France. History Aaton was founded by Eclair engineer Jean-Pierre Beauviala, whose efforts have been primarily focused on making quiet, portable motion picture hardware suitable for impromptu field use, such as for documentaries. A model for all motion picture cameras they have produced is the "cat-on-the-shoulder", a small, light, quiet motion picture camera. In the late 60's Beauviala was working as a professor of electronics in the University of Grenoble. With the project to make a movie about the evolution of the city and of its architecture, but unable to find the proper tools, Beauviala decided to create the camera himself. Though the movie would eventually be abandoned this led to the creation of Aaton in 1971. After several initial prototypes, the Aaton LTR 16 mm movie camera became available on the market in the late 1970s. It has been succeeded by several imp ...

Arricam
Arricam is a 35 mm movie camera line manufactured by Arri. Description It is Arri's flagship sync-sound camera line, replacing the Arriflex 535 line. The design was developed by Fritz Gabriel Bauer and Walter Trauninger, and is heavily derivative of the cameras Bauer created for his Moviecam company, which was bought out by Arri in the mid-1990s. As such, the Arricam is a fusion of the mechanical and intuitive design innovations of the Moviecam and the interchangeable accessories and complex electronic integration of the Arriflex. {{As of, 2006, the Arricam is considered, along with the Panaflex Millennium line, the top sync-sound camera system currently in usage, and is extremely popular amongst bigger budget feature films. The line comprises two camera body models, the ST (Studio) and LT (Lite). The Arricam ST is intended as a full-capability camera, including two camera magazine mounting configurations, whereas the Arricam LT is optimized for smaller, lightweight usage in ...

Arri
The Arri Group () 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. Hermann Simon mentioned this company in his book ''Hidden Champions of the 21st Century'' as an example of a " hidden champion". The Arri Alexa camera system was used to film Academy Award winners for Best Cinematography including ''Hugo'', ''Life of Pi'', ''Gravity'', '' Birdman'', '' The Revenant'' and '' 1917''. 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 in the Arriflex 35 c ...

Technicolor
Technicolor is a series of Color motion picture film, color motion picture processes, the first version dating back to 1916, and followed by improved versions over several decades. Definitive Technicolor movies using three black and white films running through a special camera (3-strip Technicolor or Process 4) started in the early 1930s and continued through to the mid-1950s when the 3-strip camera was replaced by a standard camera loaded with single strip 'monopack' color negative film. Technicolor Laboratories were still able to produce Technicolor prints by creating three black and white matrices from the Eastmancolor negative (Process 5). Process 4 was the second major color process, after Britain's Kinemacolor (used between 1908 and 1914), and the most widely used color process in Cinema of the United States, Hollywood during the Golden Age of Hollywood. Technicolor's #Process 4: Development and introduction, three-color process became known and celebrated for its highly s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Aperture Mask
In optics, an aperture is a hole or an opening through which light travels. More specifically, the aperture and focal length of an optical system determine the cone angle of a bundle of rays that come to a focus in the image plane. An optical system typically has many openings or structures that limit the ray bundles (ray bundles are also known as ''pencils'' of light). These structures may be the edge of a lens or mirror, or a ring or other fixture that holds an optical element in place, or may be a special element such as a diaphragm placed in the optical path to limit the light admitted by the system. In general, these structures are called stops, and the aperture stop is the stop that primarily determines the ray cone angle and brightness at the image point. In some contexts, especially in photography and astronomy, ''aperture'' refers to the diameter of the aperture stop rather than the physical stop or the opening itself. For example, in a telescope, the aperture ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Anamorphic
Anamorphic format is the cinematography technique of shooting a widescreen picture on standard 35 mm film or other visual recording media with a non-widescreen native aspect ratio. It also refers to the projection format in which a distorted image is "stretched" by an anamorphic projection lens to recreate the original aspect ratio on the viewing screen (not to be confused with anamorphic widescreen, a different video encoding concept that uses similar principles but different means). The word ''anamorphic'' and its derivatives stem from the Greek ''anamorphoun'' ("to transform"), compound of ''morphé'' ("form, shape") with the prefix ''aná'' ("back, against"). In the late 1990s and 2000s, anamorphic lost popularity in comparison to "flat" (or "spherical") formats such as Super 35 with the advent of digital intermediates; however, in the years since digital cinema cameras and projectors have become commonplace, anamorphic has experienced a considerable resurgence of popularit ...
