The Role of Gelatin

The Photographic Chemistry series was initiated by FAIC in 2015, with funding from the National Endowment for the Humanities and The Andrew W. Mellon Foundation. This series explores key elements of photographic chemistry that are essential to understanding the nature of silver-based analog photographs, their creation, and their deterioration mechanisms. These topics are critical for photograph conservators, but also of interest to photographers, artists, collectors, and other photography enthusiasts. This series of online self-study modules includes video lectures and quizzes on specific topics in the chemistry of photography. Each course contains about 5 – 15 units; each unit includes a 3 -10 minute video lecture and a brief self-assessment quiz. Study at your own pace and repeat units as needed!
