Using the daguerreotype process, John Benjamin Dancer was one of the first to produce microphotographs, in 1839. [1] He achieved a reduction ratio of 160:1. Dancer refined his reduction procedures with Frederick Scott Archer's wet collodion process, developed in 1850–51, but he dismissed his decades-long work on microphotographs as a personal hobby and did not document his procedures.
