a Stereo Realist by Campbell in 1955. Many of his photographs with it have recently been published in book form as polychromatic anaglyphs (i.e., single composite photographs viewed through colored viewing glasses). Harold Lloyd took thousands of stereo slides with his Realist and wrote the introduction to the Stereo Realist Manual published by Morgan and Lester. He also took several of the stereo pictures used in that book. Many of his pictures of Hollywood celebrities were published in the book 3D Hollywood and in Hollywood Nudes in 3-D!.
