This special film, for use with Electrostatic Dust Print Lifters, has an electrically conductive mylar coating on one side and a black coating on the opposite side. The film is placed black side down over an area suspected of dust marks. The film is then statically charged. The dust particles will then adhere to the black underside of the film, providing contrast for simplified photography. Each roll includes 30 meters 100 feet of lifting film and is 40cm 16 inches wide.
