ABSTRACT:
A light filter assembly is disclosed for a photographic camera which filter is composed of at least two light transmitting elements in combination with the lens of the camera. The elements are mounted in an assembly which in turn is capable of being mounted onto the end of the lens structure so that light entering the camera must be transmitted through both elements in turn. The element remote from the lens is made of a light transparent material while the element adjacent the lens is a polarizing filter. The assembly includes means whereby the transparent element can be stressed so that a "rainbow of colors" pattern can be superimposed on the image formed on the film. As an alternative embodiment, another polarizing filter is mounted in front of the transparent element.
