Designed by the film pioneer, Birt Acres (1854-1918), this was the first piece of film-making apparatus intended for amateur use. It used 17.5mm film, which was produced by slitting standard 35mm film in half. It was designed so that the camera could be operated secretly inside its carrying case, and it could also be set up for use as a projector.
