ABSTRACT:
A light control material generally comprising a transparent substrate for carrying a print or photographic image and a plurality of focusing elements which provide a field of view over which the brightness of the print or photographic image is enhanced. The field of view is controlled by the geometry of the focusing elements including radius, width, and degree of symmetry. By providing a field of view over which the brightness of the image is enhanced, the image may be viewed at angles which avoid the angles of specular reflection, which are usually seen as unwanted glare. Furthermore, selected portions of an image may be brightness enhanced more than others or selected portions may be brightness enhanced while others are not.
