Arthur Conan Doyle called ghost images of the deceased, who appear above relatives in photographs, a "psychic likeness." One photo from Doyle's book shows a ghost likeness of a man named, Mr. Frank Burnett. Did he appear with his relatives or did the photographer create a fake photograph to fool the family?
Arthur Conan Doyle's book, The Case for Spirit Photography, was the author's attempt to defend psychic photographers of the time, especially the Crew Circle.
