RoscoVIEW is a unique two-part window control system for film and television professionals. It consists of wide width polarizing filter installed on windows and a matching camera polarizing filter. With RoscoVIEW panels on the windows, the exterior exposure can be easily controlled by rotating the camera filter. Rotating the camera filter changes the degree of cross polarization on the window where the RoscoVIEW filter is installed. This results in 100% control of exterior brightness as seen through the window. The ambient light coming into the room or studio is reduced by only one stop.
