Wet plate photography (also known as the collodion process), is said to have been invented in 1851, almost simultaneously, by Frederick Scott Archer and Gustave Le Gray. Although the process required a portable darkroom, it combined desirable qualities of the calotype process (enabling an unlimited number of prints from a single negative) and the daguerreotype (creating a sharpness and clarity that could not be achieved with paper negatives). The technique quickly became really popular and was used for portraiture, landscape work, architectural, and other types of photography.
Probably the best result of Jacqueline's work is her brilliant book called Nebula.
