Key Features of the Rosco WindowCling
Easy to Apply
The Rosco WindowCling is available in the roll sizes (1.52 x 7.62 m) that can easily be cut to the required window size. No more need for soapy water; these window filters cling to the window with the power of static electricity and can be left for days or weeks if left undisturbed.
Stackable Window Control
Oftentimes, the brightness level of window light changes throughout the day, so filmmakers need a window control solution that they can use to adjust on the fly. In the past, stacking NDs has proven difficult because unwanted colour shifts can happen as you add layers of ND. Rosco WindowCling filters have been engineered to cling and layer on top of each other – up to eight stops! This enables filmmakers to quickly and easily adjust their window light as the brightness levels change throughout the day.
Features and Benefits of the Rosco WindowCling Lighting filter

Easily Attaches to Windows
