A little known fact was that a considerable amount of footage was taken with cameraman Von Hoffman looking toward the' rear of the camera. By religious custom, the Moroccans frowned upon reproducing their image on film, and would hide. To overcome this, Carl devised a mirror on the camera to enable him to look backwards, quieting any suspicions the populace had that they were being photographed. Furthermore, it caused many to follow his backward gaze, thereby looking directly into the camera, producing some outstanding footage.
