Developing Tank

picture info	Developing Tank A developing tank is a light-tight container used for developing film. A developing tank allows photographic film to be developed in a daylight environment. This is necessary because most film is panchromatic and therefore can not be exposed to any light during processing. Depending upon the size and type, a developing tank can hold one to many roll or sheet films. Famous brands include Paterson, Yankee, Jobo and Nikor. A film reel holds roll films in a spiral shape. The film is held evenly spaced so that the chemicals in the developing tank reach all of the film. Types General General tank support 110,126,135,120,620 format films Developing tanks and film reels for roll films come in two varieties: plastic and stainless steel. With stainless steel reels, the film is clipped to the center and then gently pinched while the reel is turned so that the film falls into the reel's grooves. With a plastic reel, the film is loaded from the outside and then wound onto the reel by rotat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

picture info	Photographic Processing Photographic processing or photographic development is the chemical means by which photographic film or paper is treated after photographic exposure to produce a negative or positive image. Photographic processing transforms the latent image into a visible image, makes this permanent and renders it insensitive to light.Karlheinz Keller et al. "Photography" in Ullmann's Encyclopedia of Industrial Chemistry, 2005, Wiley-VCH, Weinheim. All processes based upon the gelatin silver process are similar, regardless of the film or paper's manufacturer. Exceptional variations include instant films such as those made by Polaroid and thermally developed films. Kodachrome required Kodak's proprietary K-14 process. Kodachrome film production ceased in 2009, and K-14 processing is no longer available as of December 30, 2010. Ilfochrome materials use the dye destruction process. Deliberately using the wrong process for a film is known as cross processing. Common processes All photographic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Photographic Film Photographic film is a strip or sheet of transparent film base coated on one side with a gelatin photographic emulsion, emulsion containing microscopically small light-sensitive silver halide crystals. The sizes and other characteristics of the crystals determine the sensitivity, contrast, and image resolution, resolution of the film. 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 (photography), 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 be chemically photographic processing, developed into a visible photograph. In addition to visible light, all films are sensitive to ultraviolet light, X-rays, gamma rays, and particle radiation, high-energy particles. Unmodified silver halide crys ...

	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]

picture info	Meopta 16mm Development Tank Meopta - optika, s.r.o. is a Czech Republic based company that manufactures various products mainly in the field of optics. The company was once well-known for its still and movie cameras, although it no longer manufactures such products. History Optikotechna company was founded in 1933 in Přerov, Czechoslovakia. Originally established with the intention of producing a limited range of lenses and condensers, the company rapidly expanded the range of products to include enlargers, composite lenses, binoculars, riflescopes, cameras and slide projectors. After 1935, Meopta optika became a subsidiary of Zbrojovka Brno and a major supplier of military optics for the Czechoslovak Army. Company retained its focus on military production when it was seized by Germans during the occupation of Czechoslovakia as well as after WW2, when it was nationalized and renamed to Meopta – an acronym for MEchanická OPTická výrobA ("mechanical optical manufacturing"). In 1945 the company merged w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
picture info	Changing Bag A changing bag is a photographic bag specifically designed to be light-proof while in use. It is required for certain applications involving photosensitive materials when a darkroom is not available, like in the field. Common usages include removing film from its canister to put it into a developing tank, or loading and unloading sheet film holders. They are also commonly found on the set of a film, where the clapper loader may need one if shooting on location or far away from a darkroom. Usage It is handy to use when a darkroom is not available as is often the case in field shooting. It is also used in commercial photo processing labs, often to change paper. Description A changing bag has two sleeves at one end for both the user's arms, and a zipper (often more than one, for double layered changing bags) to insert the tools and film needed. There are several sizes available, from smaller ones for many still photography applications to larger bags used in large-format still phot ...

picture info	Photography Equipment Photography is the art, application, and practice of creating durable images by recording light, either electronically by means of an image sensor, or chemically by means of a light-sensitive material such as photographic film. It is employed in many fields of science, manufacturing (e.g., photolithography), and business, as well as its more direct uses for art, film and video production, recreational purposes, hobby, and mass communication. Typically, a lens is used to focus the light reflected or emitted from objects into a real image on the light-sensitive surface inside a camera during a timed exposure. With an electronic image sensor, this produces an electrical charge at each pixel, which is electronically processed and stored in a digital image file for subsequent display or processing. The result with photographic emulsion is an invisible latent image, which is later chemically "developed" into a visible image, either negative or positive, depending on the purpose ...
