Richard Benson: The Printed Picture

This website was created collaboratively by Richard Benson, photographer, teacher, and former dean of the Yale School of Art, and the Museum of Modern Art (MoMA). The site is based on The Printed Picture exhibition that was on view October 17, 2008 - July 13, 2009 at MoMA. The website provides a comprehensive education in all the primary methods used for printing pictures - relief, intaglio, planographic, and photographic. There are eight hours of Benson's recorded lectures available here, along with "additional images and details, allowing visitors to the site to draw their own path through its contents." The lectures conclude with Benson musing about the value of reproducing images.
