Transparency (photography)
In photography, reversal film or slide film is a type of photographic film that produces a positive image on a transparent base. Instead of negatives and prints, reversal film is processed to produce transparencies or diapositives (abbreviated as "diafilm" or "dia" in some languages like German or Hungarian). Reversal film is produced in various sizes, from 35 mm to roll film to 8×10 inch sheet film. A slide is a specially mounted individual transparency intended for projection onto a screen using a slide projector. This allows the photograph to be viewed by a large audience at once. The most common form is the 35 mm slide, with the image framed in a 2×2 inch cardboard or plastic mount. Some specialized labs produce photographic slides from digital camera images in formats such as JPEG, from computer-generated presentation graphics, and from a wide variety of physical source material such as fingerprints, microscopic sections, paper documents, astronomical images, ...

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 ...

Dufaycolor
Dufaycolor is an early British additive colour photographic film process, introduced for motion picture use in 1932 and for still photography in 1935. It was derived from Louis Dufay's Dioptichrome plates, a glass-based product for colour still photography, introduced in France in 1909. Both Dioptichrome and Dufaycolor worked on the same principles as the Autochrome process, but achieved their results using a layer of tiny colour filter elements arrayed in a regular geometric pattern, unlike Autochrome's random array of coloured starch grains. The manufacture of Dufaycolor film ended in the late 1950s. Process The photographic reproduction of natural colour by means of a black-and-white photograph taken and viewed through a mosaic of tiny colour filters was an idea first patented and published by Louis Ducos du Hauron in the late 1860s, but the incomplete colour sensitivity of contemporary photographic materials made it impractical at that time. John Joly independently reinve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Potato Starch
Potato starch is starch extracted from potatoes. The cells of the root tubers of the potato plant contain leucoplasts (starch grains). To extract the starch, the potatoes are crushed, and the starch grains are released from the destroyed cells. The starch is then left to settle out of solution or separated by hydrocyclones, then dried to powder. Potato starch contains typical large oval spherical granules ranging in size from 5 to 100 μm. Potato starch is a refined starch, containing minimal protein or fat. This gives the powder a clear white colour, and the cooked starch typical characteristics of neutral taste, good clarity, high binding strength, long texture, and minimal tendency to foaming or yellowing of the solution. Potato starch contains approximately 800 ppm phosphate bound to the starch; this increases the viscosity and gives the solution a slightly anionic character, a low gelatinisation temperature of approximately , and high swelling power. These propertie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panchromatic
Panchromatic emulsion is a type of black-and-white photographic emulsion that is sensitive to all wavelengths of visible light. Description A panchromatic emulsion renders a realistic reproduction of a scene as it appears to the human eye, although with no colors. Almost all modern photographic film is panchromatic. Some older types of film were orthochromatic and were not sensitive to certain wavelengths of light. As naturally prepared, a silver halide photographic emulsion is much more sensitive to blue and UV light than to green and red wavelengths. The German chemist Hermann W. Vogel found out how to extend the sensitivity into the green, and later the orange, by adding sensitising dyes to the emulsion. By the addition of erythrosine the emulsion could be made orthochromatic while some cyanine derivatives confer sensitivity to the whole visible spectrum making it panchromatic. However, his technique was not extended to achieve a fully panchromatic film until the early 190 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Additive Color
Additive color or additive mixing is a property of a color model that predicts the appearance of colors made by coincident component lights, i.e. the perceived color can be predicted by summing the numeric representations of the component colors. Modern formulations of Grassmann's laws describe the additivity in the color perception of light mixtures in terms of algebraic equations. Additive color predicts perception and not any sort of change in the photons of light themselves. These predictions are only applicable in the limited scope of color matching experiments where viewers match small patches of uniform color isolated against a grey or black background. Additive color models are applied in the design and testing of electronic displays that are used to render realistic images containing diverse sets of color using phosphors that emit light of a limited set of primary colors. Examination with a sufficiently powerful magnifying lens will reveal that each pixel in CRT, L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Autochrome Lumière
The Autochrome Lumière was an early color photography process patented in 1903 by the Lumière brothers in France and first marketed in 1907. Autochrome was an additive color "mosaic screen plate" process. It was the principal color photography process in use before the advent of subtractive color film in the mid-1930s. Prior to the Lumière brothers, Louis Ducos du Hauron utilized the separation technique to create colour images on paper with screen plates, producing natural colours through superimposition, which would become the foundation of all commercial colour photography. Descendants of photographer Antoine Lumière, inventors Louis and Auguste Lumière utilized Du Hauron's (1869) technique, which had already been improved upon by other inventors such as John Joly (1894) and James William McDonough (1896), making it possible to print photographic images in colour. One of the most broadly used forms of colour photography in the early twentieth century, autochrome was re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Auguste And Louis Lumière
The Lumière brothers (, ; ), Auguste Marie Louis Nicolas Lumière (19 October 1862 – 10 April 1954) and Louis Jean Lumière (5 October 1864 – 6 June 1948), were French manufacturers of photography equipment, best known for their ''Cinématographe'' motion picture system and the short films they produced between 1895 and 1905, which places them among the earliest filmmakers. Their screening of a single film on 22 March 1895 for around 200 members of the "Society for the Development of the National Industry" in Paris was probably the first presentation of projected film. Their first commercial public screening on 28 December 1895 for around 40 paying visitors and invited relations has traditionally been regarded as the birth of cinema. Either the techniques or the business models of earlier filmmakers proved to be less viable than the breakthrough presentations of the Lumières. History The Lumière brothers were born in Besançon, France, to Charles-Antoine Lumière (1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Color Photography
Color photography is photography that uses media capable of capturing and reproducing colors. By contrast, black-and-white or gray-monochrome photography records only a single channel of luminance (brightness) and uses media capable only of showing shades of gray. In color photography, electronic sensors or light-sensitive chemicals record color information at the time of exposure. This is usually done by analyzing the spectrum of colors into three channels of information, one dominated by red, another by green and the third by blue, in imitation of the way the normal human eye senses color. The recorded information is then used to reproduce the original colors by mixing various proportions of red, green and blue light ( RGB color, used by video displays, digital projectors and some historical photographic processes), or by using dyes or pigments to remove various proportions of the red, green and blue which are present in white light ( CMY color, used for prints on paper a ...

Release Print
A release print is a copy of a film that is provided to a movie theater for exhibition. Definitions Release prints are not to be confused with other types of prints used in the photochemical post-production process: * Rush prints, or dailies, are one-light, contact-printed copies made from an unedited roll of original camera negative immediately after processing and screened to the cast and crew in order to ensure that the takes can be used in the final film. * Workprints, sometimes called cutting copies, are, like rush prints, copies of a camera negative roll, or from selected takes. A workprint may be roughly corrected for brightness and color balance. The prints are used for editing before the negative itself is conformed, or cut to match the edited workprint. * An answer print is made either from the cut camera negative or an interpositive, depending on the production workflow, in order to verify that the grading ("timing" in American English) conforms to specifications, ...
