Using closely spaced cameras (e.g. less than 50 mm interaxial) which record less stereo effect than the eyes can see. Such a small interaxial distance can produce the effect of gigantism. If standard cameras are used, the minimum interaxial distance is typically limited by the thickness of the cameras, so a mirror or beam splitter system is often used, enabling interaxials down to millimeters.
