An apparatus for enhanced viewing of a developed image on a transparency or the like, comprising: a first image plane for positioning an image-carrying transparency for visual observation; an image detector for receiving an image from a transparency at said first image plane and producing an image signal corresponding to said image; a second image plan in optical alignment with said first image plane; a light source means positioned with respect to said first and second image planes for projecting viewing light through said first and second image planes; an image processor connected to said image detector and responsive to said image signal for producing an unsharp representation of said developed image and an unsharp image signal corresponding to said unsharp representation; and a light modulator connected to said image processor and responsive to said unsharp image signal for generating at said second image plane a pattern of attenuation corresponding to said unsharp image.
