When the DP says kill that light, the Solid Black is what goes up. It's the everyday negative fill and light block of the grip package: fly it to cut a source, tent a window, or drop the ambience on a face without touching a single lamp. Sizes run from the 4'x4' slip-on all the way to a 20'x20' for blacking out serious real estate, and every one is sewn in the USA by LA Rag House. The rag every truck runs out of first.
