Chromatte is a fabric 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 gray to the eye. The fabric contains millions of tiny glass beads that act as reflectors. When any light, such as the directional light from Reflecmedia's lens-mounted LiteRing hits the fabric, it is returned on the same path back into the camera lens. This retro-reflective process means the camera sees the apparently gray fabric as a perfectly even blue or green background.
Chromatte fabric is designed to work in conjunction with a LiteRing. The LiteRing features LEDs that are arranged in a circular casing that is positioned around the front of the camera lens, just like a regular ring light. This provides all the light required to illuminate the Chromatte background for chroma key production.
