Stereo card BWKILBURN, Littleton, NH "An angel's blessing." In the early days of the photographic medium, ghostly images were noticed in photographs. Due to long exposure times, anything that moved during the exposure was either not recorded or was recorded transparently. In 1856, Sir David Brewster, an important figure in the development of the medium, described in *The Stereoscope, Its History, Theory, and Construction* how to make ghosts appear in photographs. While Brewster clearly considered this an entertainment and a photographic trick, others, increasingly interested in the paranormal, saw it as "proof" of the existence of spirits. Photographic sessions and demonstrations of "photography of the invisible" became commonplace at the end of the 19th century.
