A new video from Shanks FX and PBS Digital Studios illustrates the process behind front screen projection. The technique, famously used by Kubrick in the “Dawn of Man” sequence of 2001: A Space Odyssey, combines foreground action with background footage to allow for substantial depth of field that cannot otherwise be achieved on location. Merely reflecting a projection off a one way mirror, and capturing the results with a camera, can produce footage that rivals most computer generated images.
