Controlling window brightness is easy with Rosco WindowCling filters. Available in three different neutral densities – and in a unique Day For Night Layer – these ultra-thin filters quickly attach to windowpanes using static electricity to attenuate the amount of windowlight in a scene. Rosco WindowCling filters are also designed to stack on top of each other in order to achieve the needed brightness level as lighting conditions change outside.

Rosco WindowCling is available in 60” x 25’ (1.52 x 7.62M) rolls and it uses the power of static electricity to adhere to windowpanes. No more need for soapy water or flat, syrupy clear soda products that attract ants. You don’t even need to pre-cut to size before installation. Just clean & buff the windows – position the WindowCling onto the pane – and then use a matte knife to cut the WindowCling to size. Because the thin WindowCling films are so lightweight, they will cling to windows for days and weeks if left undisturbed. And, because there isn’t any sort of adhesive, the WindowCling filters can be removed just as easily and re-rolled for future use on your next project.

WindowCling is available in three standard Neutral Densities – N.3, N.6 & N.9 – but it’s also available in D/N rolls that enable filmmakers to darken the windows to make it look like it’s night outside. This unique “Day For Night” layer not only lowers the overall light level of the window by 2.5 stops – it also adds a tint of steel blue to mimic the coloration of moonlight. The next time you need to transform daylight to moonlight for a Day For Night shoot - simply install the WindowCling D/N Layer onto the window, then stack the appropriate WindowCling ND on top to achieve the desired windowlight level needed for the scene.
