Rosco CalColor #4215 Blue Filter, 1/2 Stop, 48"x25' Roll

The Rosco CalColor #4215 Blue Filter is designed to cater to the spectral sensitivity of color film. It allows cinematographers to exercise selective and predictable control over the image's coloration as rendered by the film.

The 1/2 stop calibration refers to the filter's density. This filter is crafted in a 15-density format, corresponding to the familiar 1/2 stop calibration. It's a measure of how much light the filter blocks.

In color photography, the light-sensitive emulsion layer records the individual blue component of the spectrum separately. The Rosco CalColor #4215 Blue Filter fine-tunes the transmission of this color component at each light source, offering more control over the image's coloration.

This filter is designed for professional photographers and cinematographers who seek precision in their color representation and want to exercise selective and predictable control over the coloration of their images.

The Rosco CalColor #4215 Blue Filter allows for selective and predictable control over the image's coloration. This level of control, combined with its specific design for color film spectral sensitivity, makes it a game-changer for professionals in the field.
