About the Seminar
This in-person, hands-on presentation led by Robert Tat and Rick Pérez will demonstrate how to identify the most common photographic processes from the mid-19th century to the present.
Attendees will examine original examples up close, including salt prints, cased images, albumen prints, cyanotypes, silver and platinum prints, color processes, and digital prints, with a focus on distinguishing characteristics of each.
