ABSTRACT:
Apparatus is described for the detailed viewing of a strip of 35 mm slide film which is enclosed in a transparent jacket. The apparatus includes a projector with a film gate which is wide enough to pass the jacket, and which projects sufficient area to include the frame number which lies under each picture frame. The apparatus enables a person to view the details of a developed roll of slide film, in its jacket, and to select particular frames for making prints or mounted slides.
