P3D DVD Private Eye

I received some questions so I want to clarify with an example. Let's
say you were to photograph 2 still images from your DVD player. ( using
a fixed 2d SLR) The scene is a slow moving car, the movie camera is
fixed on the driver's profile as buildings move by in the background.
This is a dolly motion. Carefully choosing 2 frames from the movie (
with an estimated parallax that resembles 2-3 inch lens spacing) If the
background lacks depth in stereo, then the background scenes were added
with a green screen or some other post-camera effect. If the background
shows depth in stereo, then the set was of real construction, either a
model or an actual location. Get it? I noticed some dolly scenes from
the movie " The Haunting" are flat in stereo........so I conclude that
these interior scenes are computer generated and the camera motion adds
to the illusion of depth.
Some backdrops from the movie " Starship Troopers" are in stereo! These
places do not exist so I conclude that models were used.
