Abstract

A camera for producing 3-D motion pictures has "left eye" and "right eye" camera lenses and two corresponding film transport mechanisms. Images to be recorded on films transported by the mechanisms are reflected by semitransparent mirrors and the mechanisms and the mechanisms are arranged so that the mirrors turn the images transversely of the films. Contact prints made from the films can then simply be turned face-for-face to correct for the image reversals due to the presence of the mirrors. The contact prints are then correctly oriented for projection.
