The 24 x 36" Black Flag from Matthews has a rectangular frame with a 3/8" top pin for mounting on a grip head. It should be noted that while the fabric covers the frame almost completely, the pin and its brace are of a bare metal, silver color. Used to control natural or artificial light, the black flag can also be used to protect the camera lens from flares, control spill light from other sources, or keep light from reaching an area on the set.
Newly designed 90° flag frames will make it possible to position the instrument over the top of the set wall or use two or more units to create a box for better light control.
