Using widely spaced cameras (e.g. beyond 70mm interaxial) which record more stereo effect than the eyes can see. Such a large interaxial distance can produce the effect of miniaturization. Also used in order to achieve the effect of more stereo depth and less scale in a scene.
For stereo effects on very long shots (e.g. landscapes) interaxial camera set ups of several meters have been used (hyperstereo). One extreme example of hyperstereo is from cameras on each side of the earth to record the sun in 3D.
