Abstract: C A N A D A     Inventor: WILLIAM C. SHAW           Title: METHOD OF PRODUCING AND DISPLAYING     ABSTRACT OF THE DISCLOSURE        A method of producing and displaying a 3-D motion picture is disclosed. Two master film negatives are prepared using a camera rig employing one camera that looks directly at  the  subject  through  a  smei-transparent  mirror  and  a second camera that looks at the same subject by way of the reflective surface of the mirror, to obtain left and right eye images.  The cameras are oriented so  that  the  mirror images recorded by the second camera are turned laterally of the film in being reflected by the mirror. Contact prints are made from the negatives. Before projecting the images, the contact print from the negative that was shot by way of the mirror is turned about its longitudinal axis so that images on that print are turned laterally. Images from the two prints are simultaneously projected onto the same screen to produce a coincident 3-D image. The left and right eye images are optically coded,  for example by using optical filters that are polarized at right angles to one another.          The viewer wears spectacles having corresponding polarized lenses so that the left eye sees only projected left eye images while the right eye sees only projected right eye images.
