- William Henry Fox Talbot (1800 - 1877)(LINK)
Fox Talbot was an English member of parliament, scientist, inventor and a pioneer of photography.Fox Talbot was also an eminent mathematician, an astronomer and archaeologist, who translated the cuneiform inscriptions from Nineveh.
- The Daguerreotype & The Calotype: Photography's Parallel Histories(LINK)
There were many people interested the theoretical invention of what would later become know as photography, and several quite viable attempts had been made prior, but the Daguerreotype and the Calotype were the first to succeed in what we know today as standard photographic process.
- 1851: FREDERICK SCOTT ARCHER DISCOVERS THE WET-COLLODION PROCESS(LINK), instantaneous photography
Archer used Talbot’s calotype process which produced paper negatives but, dissatisfied with the results, he soon began his own experiments to develop a more sensitive and finely detailed process.
For his experiments Archer used collodion – a newly-discovered substance which was used as a medical dressing. A sticky solution of gun cotton in ether, collodion dried quickly to produce a tough, transparent, waterproof film.
The process he discovered was to coat a glass plate with collodion mixed with potassium iodide and then immerse the plate in a sensitising solution of silver nitrate. Exposed in the camera whilst still wet, the plate was then developed and fixed immediately. Crisp, detailed negatives were produced by exposures of only a few seconds.
Initially called the Archertype, but commonly known as the wet-collodion process, Archer’s process was to dominate photography for the next thirty years.
