CAMERA METHOD AND APPARATUS FOR RECORDING WITH SELECTED CONTRAST ABSTRACT The provision in front or the image surface of a photosensitive element of a device that selectively directs image light with increased intensity to microscopic, spaced- apart portions of the image surface yields a photograph or like record having a selectively decreased contrast. The photograph is viewed independently of its location relative to the light directing device. Changing the apparent aperture through which image light reaches the light-directing device can control the amount of contrast decrease. Further, selec- tive filtering of a portion of the incident light separately controls the contrast of high-exposure portions of the image. -1-
