"The Society was formed in 1988 as a group "dedicated to the history, science, and art of the daguerreotype," but has expanded its mission to include all forms of early photography and its processes; hence the Society's new mission and tag line: "dedicated to the history, science, and art of early photography and processes." Today, in addition to daguerreotypes, more than 90% of Society members collect other types of photographs and processes."
