The Rosco Cinegel Tough 1/4 White Diffusion Filter (48" x 25' Roll) is 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."
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.
