The collodion process, mostly synonymous with the "collodion wet plate process", requires the photographic material to be coated, sensitized, exposed, and developed within the span of about fifteen minutes, necessitating a portable darkroom for use in the field. Collodion is normally used in its wet form, but it can also be used in its dry form ...

Wet-collodion process, 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.

Apr 28, 2011 · The process is rather simple: bromide and iodide salts dissolved in collodion, which is a solution of pyroxylin in alcohol and ether. This mixture poured onto a cleaned glass plate, and allowed to sit for a few seconds.

The collodion process replaced the daguerreotype as the predominant photographic process by the end of the 1850’s. It was eventually replaced in the 1880’s with the introduction of the gelatin silver process.

The translucency of paper posed an obstacle for relaying detail from negative to positive. This problem was solved in 1848 by the British sculptor-turned-photographer Frederick Scott Archer, who invented the wet collodion process, a means of producing negative images on glass plates.

Mar 2, 2010 · The wetplate collodion process. This process is used to make different image types: The Ambrotype, the Tintype (also known as the Ferrotype), and a negative. In fact while the first three appear to be auto-positive images they are in fact thin negatives that via the wet plate process are able to be viewed as positives.

For over thirty years, from the 1850s to the 1880s, the wet plate collodion process was the most commonly practiced photographic method around the world. The Ambrotype process (from Greek “ambrotos”, “immortal”) or amphitype was invented by James Ambrose Cutting (1814-1867) in 1854. Cutting was a 19th century American photographer and inventor.

Dec 2, 2023 · The Wet-Collodion (or wet-plate collodion) process is an early negative-positive photographic process. It was invented in 1850, and published in 1851 by Frederick Scott Archer, although a Frenchman, Gustave Le Gray may have discovered the process independently at around the same time.

Sally Mann discusses her photographic process of using collodion, a syrupy solution of nitrocellulose, to prepare a negative.

Jan 21, 2014 · Collodion had been developed as a medical dressing and was used as such in the Crimean War. collodion was created by dissolving explosive guncotton, or nitrocellulose (ordinary carded cotton soaked in nitric and sulfuric acids, then …
