Rosco #8609 WindowCling ND9
An optically clear N.9 neutral density filter that reduces the incident light level of windowlight by three stops. T% = 15%
WindowCling is manufactured using an ultra-thin, Hi-Tack polyester that enables it to temporarily attach to glass or plastic windowpanes via static electricity. This makes it a simple solution for modifying the amount of daylight coming through the window. It’s available in three standard neutral densities – ND3 (1-stop), ND6 (2-stops) & ND9 (3 stops) – as well as a unique Day For Night (D/N) layer – and it comes in 60” x 25’ (1.52 x 7.62M) rolls.
