17.5mm Film
17.5 mm film was a film gauge for as many of eight types of motion picture film stock, generally created by splitting unperforated 35 mm film. History 17.5 mm film was first documented in 1898 with the creation of the Birtac camera, and subsequently went through several different iterations up until the end of World War II, when Kodak's 16 mm film and 8 mm film largely took its place in terms of popularity. In addition to original pioneering experiments, 17.5 mm film was used during World War II to use existing 35 mm stock more economically. Afterward, this format continued to be used primarily in developing countries such as India, or for projects where usage of regular 35 mm film would have been too expensive. Partial list Birtac The British-American photographer and inventor Birt Acres split 35 mm film in half for his Birtac camera-projector in 1898. The film used had a single row of perforations running down the left side of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Film Gauge
Film gauge is a physical property of photographic or motion picture film stock which defines its width. Traditionally, the major movie film gauges are 8 mm, 16 mm, 35 mm, and 65/70 mm (in this case 65 mm for the negative and 70 mm for the release print; the extra five millimeters are reserved for the magnetic soundtrack). There have been other historic gauges in the past, especially in the silent era, most notably 9.5 mm film, as well as a panoply of others ranging from 3 mm to 75 mm. Larger film gauge is generally associated with higher image quality, higher image detail, greater materials expense, heavier camera equipment, larger and most costly projection equipment, as well as greater bulk and weight for distribution and storage (both interim and archival). See also *Film format A film format is a technical definition of a set of standard characteristics regarding image capture on photographic film for still images or film stock for filmmaking. ...

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] |
35 Mm 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. F ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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 ...

Warwick Trading Company
The Warwick Trading Company was a British film production and distribution company, which operated between 1898 and 1915. History The Warwick Trading Company had its origins in the London office of Maguire and Baucus, a firm run by two American businessmen who, from 1894, acted as agents marketing films and projectors produced by Thomas Edison. In 1897, they also acquired the rights to distribute films produced by the Lumière brothers. Later that year, Charles Urban was appointed managing director. Urban was dissatisfied with the current location of the offices, in Broad Street, and proposed a move to a building in Warwick Court, which was nearer to like-minded businesses such as that of Robert W. Paul. Urban also suggested a simultaneous name change, as he felt the current name was difficult to do business with. The company was thus rebranded as the Warwick Trading Company, after the address of its new offices in Warwick Court. The new company was officially registered in May ...
