Rosco Roscolux #4260 CalColor Blue Filter is designed specifically to the spectral sensitivity of color film. In color photography, three light-sensitive emulsion layers separately record the individual blue, green and red components of the spectrum. CalColor filters adjust the transmission of these color components at the individual light source in a familiar and reliable manner. As a result, the cinematographer can exercise selective and predictable control over the image's coloration as rendered by the film.
