Different photographers have different preferences: some love shooting landscapes, others enjoy portraits, and some specialize in still life. But have you ever heard of a photographer who exclusively captures the moment when a TV turns off? German photographer Stephan Tillmans has precisely such an unusual subject. He enjoys capturing the instant when a CRT television is turned off. Don't laugh—April Fool's Day is over, and this isn't a joke. His work has even been exhibited before.
