Serios would use what he called a "gizmo," a tube of paper placed against the camera lens. He said this helped him to focus his mental energy and direct it toward the film. He also used something he didn't tell anyone about—a tiny tube about one inch long and one-half inch in diameter. This tube had a tiny magnifying lens at one end. In the other end one could insert a piece cut from a standard 35mm slide. Lined up properly, this device projected the image on the cut piece of transparency onto the film of the Polaroid camera. The device was small enough to be concealed in the palm of the hand, so it could be used even when the larger paper "gizmo" wasn't around to conceal it.
