Well made opaque fabric with a rigid frame, this 36”(90cm) X 36”(90cm) top hinge floppy opens to 36”(90cm)X 72”(180cm) is very convenient for controlling light as they double in size by detaching the velcro. Works well as a courtesy shade for the camera or monitor outdoors or to block light from a doorway with no door or to control light on talent in front of green screen lighting.
