Rosco Cinegel diffusion material, Silent Frost, 20" x 24" Sheet. Cinegel filters are meticulously manufactured on a heat-resistant base polymer utilizing a patented deep-dyed technology. On-line computerized colorimetry continuously monitors color and density against strict standards, thus assuring a reliable and consistent product.
Lighting fixtures for film and video production usually function by means of a reflector that gathers the light from a point source and focuses it through a lens. The result is a beam that has a high level of intensity or "punch". But these fixtures also present a number of drawbacks: the projected beam field may be uneven in intensity, the beam edge may be too harsh, or the hard shadows created by the beam may be objectionable or unflattering to the subject.
Placed in the beam path, diffusion materials modify the harsh quality of the beam by spreading or dispersing the light. This effectively softens the beam and alters its shadow-casting properties. In addition, diffusion reduces the contrast between highlight and shadow areas.
