Siderotype
Siderotype is an iron-based photographic print. The term was coined by Sir John Frederick William Herschel. A short list of processes defined as siderotypes is as follows: amphitype, argentotype, argyrotype, aurotype, breath print, Brown Line, chromatic photo, chrysotype, cyanotype, ferrogallic process, kallitype, kelaenotypeNakahara's Process palladiotype, Architectural reprography, Pellet print, Phipson's process, platinotype, printout platinum, satista print, sepia platinotype, sepiatype and Van dyke brown, vandyke.

Aurotype
Aurotype is a Monochrome printmaking, monochrome photographic printing process that uses Gold chloride, potassium ferricyanide and potassium ferrocyanide, ferrocyanide. It was described in 1844 by Robert Hunt (scientist), Robert Hunt. It is a member of the Siderotype family of processes.

Sir John Frederick William Herschel
Sir John Frederick William Herschel, 1st Baronet (; 7 March 1792 – 11 May 1871) was an English polymath active as a mathematician, astronomer, chemist, inventor, experimental photographer who invented the blueprint and did botanical work. Herschel originated the use of the Julian day system in astronomy. He named seven moons of Saturn and four moons of Uranus – the seventh planet, discovered by his father Sir William Herschel. He made many contributions to the science of photography, and investigated colour blindness and the chemical power of ultraviolet rays. His ''Preliminary Discourse'' (1831), which advocated an inductive approach to scientific experiment and theory-building, was an important contribution to the philosophy of science. Early life and work on astronomy Herschel was born in Slough, Buckinghamshire, the son of Mary Baldwin and astronomer William Herschel. He was the nephew of astronomer Caroline Herschel. He studied shortly at Eton College and S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Printout Platinum
''Hard Copy'' is an American tabloid television show that ran in syndication from 1989 to 1999. ''Hard Copy'' was aggressive in its use of questionable material on television, including gratuitous violence. The original hosts of ''Hard Copy'' were Alan Frio and Terry Murphy. Frio left the series after the 1990–91 season and was succeeded by Barry Nolan in the fall of 1991. Nolan and Murphy would stay until after the 1997–98 season, when they both departed. In the show's final season, Kyle Kraska took over as the sole host. ''Hard Copy'' was produced and distributed by Paramount Domestic Television and, for much of its time on air, was often aired with its sister show, the Hollywood news program ''Entertainment Tonight'' as part of an hour-long programming block sold to local stations. Overview ''Hard Copy'' was a tabloid show that aired footage and news about celebrities and everyday people. Also featured were interviews with various newsmakers. 1992 Elton John law ...

Platinotype
Platinum prints, also called ''platinotypes'', are photographic prints made by a monochrome printing process involving platinum. Platinum tones range from warm black, to reddish brown, to expanded mid-tone grays that are unobtainable in silver prints. Unlike the silver print process, platinum lies on the paper surface, while silver lies in a gelatin or albumen emulsion that coats the paper. As a result, since no gelatin emulsion is used, the final platinum image is absolutely matte with a deposit of platinum (and/or palladium, its sister element which is also used in most platinum photographs) absorbed slightly into the paper. Platinum prints are the most durable of all photographic processes. The platinum group metals are very stable against chemical reactions that might degrade the print—even more stable than gold. It is estimated that a platinum image, properly made, can last thousands of years. Some of the desirable characteristics of a platinum print include: * The re ...

Architectural Reprography
Architectural reprography, the reprography of architectural drawings, covers a variety of technologies, media, and supports typically used to make multiple copies of original technical drawings and related records created by architects, landscape architects, engineers, surveyors, mapmakers and other professionals in building and engineering trades. Within the context of archival preservation, the custodians of architectural records must consider many aspects of identification and care when managing the artifactual nature of these materials. Storage containers, handling, paper and chemical compositions and interactions, ultraviolet light exposure, humidity, mold, and other agents of potential harm all interact to determine the longevity of these documents. As well, architectural reprographic drawings are often in very large formats, making storage and handling decisions especially complex. History With the rise of the professionalized practice of western architecture in the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kallitype
Kallitype is a process for making photographic prints. Patented in 1889 by W. W. J. Nicol (1855-1929), the Kallitype print is an iron-silver process. A chemical process similar to the Van Dyke brown based on the use of a combination of ferric and silver salts. While Van Dyke brown and argyrotype use ferric ammonium citrate, the light-sensitive element used for the Kallitype is ferric oxalate. The use of ferric oxalate allows for both extended shadow definition (higher DMAX) and contrast control. Many developing solutions can be used to give a different image color (brown, sepia, blue, maroon and black). Kallitype images generally have a richer tonal range than the cyanotype. These prints were popular in the 19th century, and then their popularity faded away. Sometimes known as "the poor man's platinum print", when the image is toned in platinum or palladium the result is nearly chemically identical to a true Platinotype. It is believed that many Kallitypes were passed off as true ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
