Salted paper prints
The salted paper technique was created in the mid-1830s by English scientist and inventor Henry Fox Talbot.
The salt print was the dominant paper-based photographic process for producing positive prints (from negatives) from 1839 until approximately 1860. -
Calotype
Calotype is an early photographic process introduced in 1841 by William Henry Fox Talbot, using paper coated with silver iodide. -
Cyanotype
Cyanotype is a photographic printing process that produces a cyan-blue print.
The English scientist and astronomer Sir John Herschel discovered the procedure in 1842. -
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. -
Ambrotype
Ambrotype is a positive photograph on glass made by a variant of the wet plate collodion process.
The ambrotype was introduced in the 1850s.
It was invented by Frederick Scott Archer. -
Gum print
Gum printing is a way of making photographic reproductions without the use of silver halides.
It was invented in the 1850s. -
Wet plate process
wet plate process is a early photographic technique invented by Englishman Frederick Scott Archer in 1851.
The process involved adding a soluble iodide to a solution of collodion (cellulose nitrate) and coating a glass plate with the mixture. -
Collodion
In 1851, Frederick Scott Archer, an Englishman, discovered that collodion could be used as an alternative to egg white on glass photographic plates.
Collodion reduced the exposure time necessary for making an image. -
Tintype
A tintype is a photograph made by creating a direct positive on a thin sheet of metal coated with a dark lacquer or enamel and used as the support for the photographic emulsion.
The process was first described by Adolphe-Alexandre Martin in France in 1853. -
Carbon print
A carbon print is a photographic print with an image consisting of pigmented gelatin, rather than of silver or other metallic particles suspended in a uniform layer of gelatin, as in typical black-and-white prints, or of chromogenic dyes, as in typical photographic color prints.
It was invented by Alphonse Poitevin in 1855. -
Woodburytype
A Woodburytype is both a printing process and the print that it produces. In technical terms, the process is a photomechanical rather than a photographic one, because sensitivity to light plays no role in the actual printing.
The Woodburytype process was invented by Walter B. Woodbury and patented in 1864. -
Platinum print
Platinum prints are photographic prints made by a monochrome printingprocess involving platinum.
William Willis was the first to patent the this process in 1873
