Frederick Scott Archer
Archer came to photography through sculpture. In 1847, he began photographing models for his work, looking for greater definition than paper negatives could offer. His experiments with collodion and glass led him to the transformation we still practise at the studio.
His account of the wet collodion process appeared in The Chemist in 1851. Archer chose not to patent the discovery. Other photographers could follow his description and use the process in their own workshops.
A wet plate set a strict condition: preparation, exposure and development all had to be completed before the collodion dried. In 1853, Archer made a portable folding camera with a built-in darkroom. The darkroom could now travel with the camera.
