A-Minima
The A-Minima is a Super 16 movie camera that was introduced by Aaton in 1999. Touted as the smallest reflex viewfinder movie camera at the time, the camera is distinguished by its low-profile form-factor. It has a size comparable to a small prosumer video camera, and weights including film and battery. The A-Minima was the first Super 16 only camera. In order to accommodate the camera design, Aaton worked with Eastman Kodak to create a specially designed flexible flange daylight spool. Because of the spool's particular design and the fact that the camera requires A-wind 16 mm film, the A-Minima can only use Kodak film stock, manufactured specifically for use with the A-Minima. The 200 foot length (approximately 5.5 minutes at 24 frame/s) and slightly noisy sound rating of 29 dB make it convenient as a B-camera or second unit camera; however, the small size and ease of use, along with an integrated AatonCode timecode A timecode (alternatively, time code) is a seq ...

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 ...

16 Mm Film
16 mm film is a historically popular and economical gauge of film. 16 mm refers to the width of the film (about inch); other common film gauges include 8 and 35 mm. It is generally used for non-theatrical (e.g., industrial, educational, televisual) film-making, or for low-budget motion pictures. It also existed as a popular amateur or home movie-making format for several decades, alongside 8 mm film and later Super 8 film. Eastman Kodak released the first 16 mm "outfit" in 1923, consisting of a camera, projector, tripod, screen and splicer, for US$335 (). RCA-Victor introduced a 16 mm sound movie projector in 1932, and developed an optical sound-on-film 16 mm camera, released in 1935. History Eastman Kodak introduced 16 mm film in 1923, as a less expensive alternative to 35 mm film for amateurs. The same year the Victor Animatograph Corporation started producing their own 16 mm cameras and projectors. During the 1920s, the fo ...

Movie Camera
A movie camera (also known as a film camera and cine-camera) is a type of photographic camera that rapidly takes a sequence of photographs, either on an image sensor or onto film stock, in order to produce a moving image to project onto a movie screen. In contrast to the still camera, which captures a single image at a time, by way of an intermittent mechanism, the movie camera takes a series of images; each image is a ''frame'' of film. The strips of frames are projected through a movie projector at a specific frame rate (number of frames per second) to show a moving picture. When projected at a given frame rate, the persistence of vision allows the eyes and brain of the viewer to merge the separate frames into a continuous moving picture. History An interesting forerunner to the movie camera was the machine invented by Francis Ronalds at the Kew Observatory in 1845. A photosensitive surface was drawn slowly past the aperture diaphragm of the camera by a clockwork mechanism to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
View Factor
In radiative heat transfer, a view factor, F_, is the proportion of the radiation which leaves surface A that strikes surface B. In a complex 'scene' there can be any number of different objects, which can be divided in turn into even more surfaces and surface segments. View factors are also sometimes known as configuration factors, form factors, angle factors or shape factors. Summation of view factors Because radiation leaving a surface is conserved, the sum of all view factors ''from'' a given surface, S_i, is unity: :\sum_^n = 1 For example, consider a case where two blobs with surfaces ''A'' and ''B'' are floating around in a cavity with surface ''C''. All of the radiation that leaves ''A'' must either hit ''B'' or ''C'', or if ''A'' is concave, it could hit ''A''. 100% of the radiation leaving ''A'' is divided up among ''A'', ''B'', and ''C''. Confusion often arises when considering the radiation that ''arrives'' at a ''target'' surface. In that case, it generally does n ...

Prosumer
A prosumer is an individual who both consumes and produces. The term is a portmanteau of the words '' producer'' and ''consumer''. Research has identified six types of prosumers: DIY prosumers, self-service prosumers, customizing prosumers, collaborative prosumers, monetised prosumers, and economic prosumers. The terms ''prosumer'' and ''prosumption'' were coined in 1980 by American futurist Alvin Toffler, and were widely used by many technology writers of the time. Technological breakthrough and a rise in user participation blurs the line between production and consumption activities, with the consumer becoming a prosumer. Definitions and contexts Prosumers have been defined as "individuals who consume and produce value, either for self-consumption or consumption by others, and can receive implicit or explicit incentives from organizations involved in the exchange." The term has since come to refer to a person using commons-based peer production. In the digital and online wo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Video Camera
A video camera is an optical instrument that captures videos (as opposed to a movie camera, which records images on film). Video cameras were initially developed for the television industry but have since become widely used for a variety of other purposes. Video cameras are used primarily in two modes. The first, characteristic of much early broadcasting, is live television, where the camera feeds real time images directly to a screen for immediate observation. A few cameras still serve live television production, but most live connections are for security, military/tactical, and industrial operations where surreptitious or remote viewing is required. In the second mode the images are recorded to a storage device for archiving or further processing; for many years, videotape was the primary format used for this purpose, but was gradually supplanted by optical disc, hard disk, and then flash memory. Recorded video is used in television production, and more often surveillance and ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Eastman Kodak
The Eastman Kodak Company (referred to simply as Kodak ) is an American public company that produces various products related to its historic basis in analogue photography. The company is headquartered in Rochester, New York, and is incorporated in New Jersey. Kodak provides packaging, functional printing, graphic communications, and professional services for businesses around the world. Its main business segments are Print Systems, Enterprise Inkjet Systems, Micro 3D Printing and Packaging, Software and Solutions, and Consumer and Film. It is best known for photographic film products. Kodak was founded by George Eastman and Henry A. Strong on May 23, 1892. During most of the 20th century, Kodak held a dominant position in photographic film. The company's ubiquity was such that its " Kodak moment" tagline entered the common lexicon to describe a personal event that deserved to be recorded for posterity. Kodak began to struggle financially in the late 1990s, as a result of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flange
A flange is a protruded ridge, lip or rim (wheel), rim, either external or internal, that serves to increase shear strength, strength (as the flange of an iron beam (structure), beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe (fluid conveyance), pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a railroad car, rail car or tram train wheel, wheel, which keep the wheels from derailment, running off the rail profile, rails). Flanges are often attached using bolts in the pattern of a bolt circle. The term "flange" is also used for a kind of tool used to form flanges. Plumbing or piping A flange can also be a plate or ring to form a rim at the end of a pipe when fastened to the pipe (for example, a closet flange). A blind flange is a plate for covering or closing the end of a pipe. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Film Stock
Film stock is an analog medium that is used for recording motion pictures or animation. It is recorded on by a movie camera, developed, edited, and projected onto a screen using a movie projector. It is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast and resolution of the film.Karlheinz Keller et al. "Photography" in Ullmann's Encyclopedia of Industrial Chemistry, 2005, Wiley-VCH, Weinheim. The emulsion will gradually darken if left exposed to light, but the process is too slow and incomplete to be of any practical use. Instead, a very short exposure to the image formed by a camera lens is used to produce only a very slight chemical change, proportional to the amount of light absorbed by each crystal. This creates an invisible latent image in the emulsion, which can ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Decibel
The decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel (B). It expresses the ratio of two values of a power or root-power quantity on a logarithmic scale. Two signals whose levels differ by one decibel have a power ratio of 101/10 (approximately ) or root-power ratio of 10 (approximately ). The unit expresses a relative change or an absolute value. In the latter case, the numeric value expresses the ratio of a value to a fixed reference value; when used in this way, the unit symbol is often suffixed with letter codes that indicate the reference value. For example, for the reference value of 1 volt, a common suffix is " V" (e.g., "20 dBV"). Two principal types of scaling of the decibel are in common use. When expressing a power ratio, it is defined as ten times the logarithm in base 10. That is, a change in ''power'' by a factor of 10 corresponds to a 10 dB change in level. When expressing root-power quantities, a change in ''ampl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Second Unit
Second unit is a discrete team of filmmakers tasked with filming shots or sequences of a production, separate from the main or "first" unit. The second unit will often shoot simultaneously with the other unit or units, allowing the filming stage of production to be completed faster. Function The functions of the second unit vary, but typically the first unit films the key face-to-face drama between the principal actors. Two frequent ways a second unit is used are: * Action sequences: Action sequences are often filmed in discrete locations, using stunt performers, rather than the principal cast, and requiring significantly different filming arrangements than for ordinary scenes. Therefore, they are an opportunity for second unit shooting. * "Pick-ups": After the main unit has finished on a set or location, there may be shots that require some or all of this setting as background but that do not require the principal actors. These shots may include things such as close-ups, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Timecode
A timecode (alternatively, time code) is a sequence of numeric codes generated at regular intervals by a timing synchronization system. Timecode is used in video production, show control and other applications which require temporal coordination or logging of recording or actions. Video and film In video production and filmmaking, SMPTE timecode is used extensively for synchronization, and for logging and identifying material in recorded media. During filmmaking or video production shoot, the camera assistant will typically log the start and end timecodes of shots, and the data generated will be sent on to the editorial department for use in referencing those shots. This shot-logging process was traditionally done by hand using pen and paper, but is now typically done using shot-logging software running on a laptop computer that is connected to the timecode generator or the camera itself. The SMPTE family of timecodes are almost universally used in film, video and audio produc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
