curious to find out if I will get true 3-D from two stills, or whether I
will just get cheap "cardboard cutout" effect instead (as if the rotation
might have been synthesized).  I guess I better try it and see!<

Theoretically, a couple of frames from the commercial should produce an
excellent true stereo effect. In the simplest form, the effect is created
by setting up a whole buncha cameras side by side and firing them all
simultaneously, then optically creating a sequence made up of each frame,
one after the other. Because the sequence now plays over a period of time,
the change in position reads as a moving camera, although of course only
the "camera position" and not the action changes since each of the "frames"
was actually shot at the same time. Movement before and after the "pan" is
achieved by having an actual motion picture camera as the first and last
camera in the chain.
