Anotations

Scope note:

A type of collodion process in which the binder was dried before exposure or contained a hygroscopic agent to retain sufficient moisture to allow processing after an extended period of time; an improvement on the wet collodion process because it alleviated the need for a portable darkroom. Used to produce negatives and lantern slides.
