A recent poll conducted by CNN revealed that one third of the people believed in ghosts, and that many of those claim they’ve seen one. At the same time, interest in spirit photography - events in which images of the dead are caught on film - has never been higher. The phenomenon is as old as photography itself, dating back to the 1860s. Spirit photography has been riddled with controversy and fraud, yet many believe it to be one of the few methods of capturing ghostly phenomenon that approaches scientific methodology. Magazines devoted to spirit photography proliferate throughout Asia, and new internet sites devoted to the subject spring up every day. New York’s Metropolitan Museum of Art recently hosted an exhibit devoted to spirit photography, called “The Perfect Medium: Photography and the Occult.” This intriguing and foreboding subject is a key element of the psychological thriller “Shutter”, from executive producers of “The Grudge” and “The Ring.” In “Shutter”, a newly married couple discovers disturbing, ghostly images in photographs they develop after a tragic accident. Fearing the manifestations may be connected, they investigate, only to learn that some mysteries are better left unsolved - and that a past mistake can lead to an eternity of vengeance.
