lens reflex (TLR) camera  (appears to be a Rolleicord). The black & white "snapshots" stills  that appear on the screen during this scene are rectangular in  shape. However, the Rolleicord and other TLR camera of this era only  produced square images on either 120 (or 620) size medium format  film. (In mitigation, square images are frequently cropped to a  rectangular format.)
