This kit consists of an 8x8 feet Non-Backed Chromatte Curtain with Small Green LiteRing. The LiteRing connects to the camera with a specially designed adapter ring. With the LiteRing in place, you have a perfectly aligned and corrected light source to perfectly key the special background material. The Reflecmedia Chromatte fabric is designed specifically for use as a background for Chroma key production. Unlike conventional Chroma key fabrics that are usually blue or green in color, in ambient light Chromatte is grey to the eye. The fabric contains millions of tiny glass beads that act as reflectors: when the directional light from Reflecmedia’s lens-mounted LiteRing – hits the fabric, it is returned on the same path back into the camera’s lens. This retro-reflective process means the camera ‘sees’ the apparently grey fabric as a perfectly even blue or green background.
