Researcher and artist Dr. Christopher Webster presents an interesting website of paranormal photography (especially the relationship between the crisis in belief and spirit photographs in the nineteenth century). Webster describes his work as being "to some degree a visual equivalent of automatic writing." He explores photography as a tool for recording the paranormal.
