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 p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dye-transfer Process
Dye transfer is a continuous-tone color photographic printing process. It was used to print Technicolor films, as well as to produce paper colour prints used in advertising, or large transparencies for display. History The use of dye imbibition for making full-color prints from a set of black-and-white photographs taken through different color filters was first proposed and patented by Charles Cros in 1880.Pénichon, Sylvie (2013). "Twentieth-Century Color Photographs: Identification and Care". The Getty Conservation Institute, Los Angeles. pp. 127-131. It was commercialized by Edward Sanger-Shepherd, who in 1900 was marketing kits for making color prints on paper and slides for projection. Imbibition printing was initially in monochrome. The basic underlying principle is that bichromate development of a silver gelatine photographic emulsion (not strictly a real chemical emulsion) results in the gelatine being differentially tanned or hardened in proportion to the exposure rec ...

Albumen Print
The albumen print, also called albumen silver print, was published in January 1847 by Louis Désiré Blanquart-Evrard, and was the first commercially exploitable method of producing a photographic print on a paper base from a negative. It used the albumen found in egg whites to bind the photographic chemicals to the paper and became the dominant form of photographic positives from 1855 to the start of the 20th century, with a peak in the 1860–90 period. During the mid-19th century, the carte de visite became one of the more popular uses of the albumen method. In the 19th century, E. & H. T. Anthony & Company were the largest makers and distributors of albumen photographic prints and paper in the United States.Welling, William. Photography in America (1978 & 1987) Creation process # A piece of paper, usually 100% cotton, is coated with an emulsion of egg white (albumen) and salt (sodium chloride or ammonium chloride), then dried. The albumen seals the paper and creat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Albertype
An Albertype is a picture printed from a type of gelatine-coated plate produced by means of a photographic negative. The process was invented by Josef Albert, a German photographer who owned and directed a studio and photo lab in Augsburg, Germany. The technique is similar to collotype, but substitutes the gel plate for the lithographic stone used in collotype. Heliotype, invented in 1871 by Edwards, is another similar process. Albert's innovation was to replace the copper or stone with glass, construct a mechanical press, and cover it with another gel layer, silicate mixed with gelatin, in order to produce about two thousand prints from each plate using etching presses and hand rollers. This new process was presented at the 1868 Photographic Exhibition in Hamburg and “albertype,” was the name given by Joseph Albert.The Historical Society of Pennsylvani"Albertype Company This technique was adopted by publishers creating thousands of postcards and viewbooks. In 1890 Adolp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Acetate Film
Cellulose acetate film, or safety film, is used in photography as a base material for photographic emulsions. It was introduced in the early 20th century by film manufacturers and intended as a safe film base replacement for unstable and highly flammable nitrate film. Cellulose diacetate film was first created by the German chemists Arthur Eichengrün and Theodore Becker, who patented it under the name Cellit, from a process they devised in 1901 for the direct acetylation of cellulose at a low temperature to prevent its degradation, which permitted the degree of acetylation to be controlled, thereby avoiding total conversion to its triacetate. Cellit was a stable, non-brittle cellulose acetate polymer that could be dissolved in acetone for further processing. A cellulose diacetate film more readily dissolved in acetone was developed by the American chemist George Miles in 1904. Miles's process (partially hydrolysing the polymer) was employed commercially for photographic film in ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
One-light A one-light is a timed workprint made using a ''single'' setting of the three lights (red, green and blue) used to make a color film print. Since a fully timed print requires the presence of a skilled person called a color timer (US) or film grader' (UK), a one-light print is more economical for printing dailies In filmmaking, dailies are the raw, unedited footage shot during the making of a motion picture. The term comes from when movies were all shot on film because usually at the end of each day, the footage was developed, synced to sound, and print ... (positive) from rushes (negative). Cinematographers often require one-light workprints to better judge their film exposures. Cinematography Photographic techniques {{filmmaking-stub ... [...More Info...] |
