Robert occasionally collaborated on projects with his brother, Doug, a photographer and filmmaker. In this photo-collage, made by sandwiching two negatives together, the artist is portrayed as a manipulator of light — changeable, dramatic and ghost-like. Doug was influenced by American photographer Duane Michaels, famous for his photo sequences that use superimposition to create a fantastic or haunting effect. In this photo experiment, Robert holds a lighted bulb in different positions, lighting his face from the side, from the front, from below, each time creating a new effect.
