The LiteRing is a circular arrangement of bright blue or green light-emitting diodes (LEDs) mounted around the camera lens. The LiteRing provides all the necessary source light to illuminate the Chromatte fabric for keying. Manufactured in two sizes, it is compatible with most digital and professional video camera lenses. The AC-powered LiteRing Controller (LRC) allows adjustment of the light intensity required for optimal keying results. The ideal shooting distances depend on several variables, including ambient light levels, choice of keying applications, camera quality and shooting formats. As a general rule, the subject should be more than 2.4 m from the camera to avoid a blue cast. The maximum distance is approximately 18 m.
