FILM-TECH SCREENING ROOM (CURRENT / PLANO) Plano, TX
Here the room is being EQ'd while Dan replaces a bulb that has already died. You can see here that when the curtains are open they pull behind the black so the only thing the viewer sees when the curtains are open and the lights are down is the screen surrounded only by black. The masking here is side as well as bottom, to be able to precisely obtain any aspect ratio needed. (The doors will be painted black soon.)
