Scope

Included in this guide are descriptions and examples of photographic processes represented in the collections of the Prints and Photographs Division. The information is meant to help people understand the history, function, and production techniques of original photographs viewed either at Reading Room tables or in our online catalog as digital reproductions.

Some processes are direct-image positives, while others are printed from various types of negatives. We have provided a Chronological Listing to indicate which processes were in use at the same time and to assist with dating images.
