What is Wet Plate Collodion?

Wet plate collodion is a mid-1800s photographic process invented in 1851 by English sculptor, Frederick Scott Archer. The in-camera process involves a complex series of steps, each using a specialized chemical solution. Wet plate collodion is a by-inspection process, meaning the decision to end one step and begin the next is literally in the hands of the photographer.

A collodion image is made on a glass or metal plate. The image most be created while the plate is still wet with chemicals, so a portable darkroom is a necessity in the field.
