Taken with a shift of the camera and tripod. The stereo pair
can be viewed by starring beyond the screen and letting your eyes
turn out to parallel and beyond. You will need to superimpose the
images with the Left image into your left eye and the right into
your right eye. The result will be three images
seen with the centre one in 3d or stereo. Moving back from the screen
will also help to do the "superimpose trick" or use a black card held
at your nose. If you Cross your eyes (left image into right eye etc)
the stereo 3d will appear weirdly reversed.
