Abstract: A fluid-containing lens filter (20) for modifying images in photographic, video and motion picture cameras in the form of a filter housing (22) that consists of a front plate (24), a back plate (26) with a bottom edge (28) and a pair of opposed side edges (30). The edges are juxtaposed between the front plate (24) and the back plate (26), leaving a void therebetween. The bottom edge (28) and side edges (30) are bonded to the front and back forming a fluid-tight chamber (36) within the filter housing. A fluid (38), having light modifying qualities, is disposed within the chamber (36) such that color, translucency, and clarity are altered to create a supplementary visual effect on an image viewed by the camera. Various types of fluids may be used in the filter, affecting the image by means of color pigment (40), particles (42), chemical reactions (48) and myriad different combinations thereof. In addition, particles within the fluids may be illuminated by light sources (54) directed to the edges.
