Off-camera flash as High Art: Julius von Bismark, an artist in Berlin, is playing with snap-happy tourists by injecting words into their photos.
He cut a hole in the back of an old film camera and stuck a slaved flash into it. By writing words onto transparent plastic and sliding the sheet into a slot near the film plane, the whole rig now works backwards and becomes a projector. By leaving the shutter open and slaving the rear flash, he can now project those words onto the subject of someone else’s photo when their flash trips his flash.
