Rosco CalColor #4530 Yellow Filter, 1 Stop, 48"x25' Roll

The Rosco CalColor #4530 Yellow Filter (1 Stop, 48"x25' Roll) is designed specifically to the spectral sensitivity of color film. This filter color is designed in 30 density, corresponding to the familiar 1 stop calibration. In color photography, three light-sensitive emulsion layers separately record the individual blue components of the spectrum.

CalColor filter adjusts 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.
