Thomas Jefferson was fascinated with the latest advancements in technology such as the camera obscurer, which allows the photographer to project a reversed silhouette of an image onto a piece of paper. Join Poplar Forest and photographer Greg Farley to explore the history of the rudimentary form of photography that laid the foundation for generations of technological advancements in the field from its inception to today’s digital methods. See how these cameras worked through demonstrations, and learn how they were used to preserve history in a way that words alone never could. Admission is $30 and includes admission to the property and self-guided exhibits; reservations are encouraged as spots for each seminar are limited.
