At its most popular in the 19th century, the camera obscura room was not only viewed as educational and entertaining but was a metaphor (as was photography) for the voyeur. It was a device to see without being seen, to spy on the unaware. The camera obscura on the Isle of Man was said to overlook the cliff walk favored by courting couples. By the end of the 20th century, the camera obscura’s popularity had decreased. At present there are very few room-size camera obscuras existing in the U.S. www.TrefethenStudios.com
