The Reflecmedia LiteRing is a circular arrangement of bright blue or green light-emitting diodes (LEDs) mounted around the camera lens. The LiteRing provides all the source light necessary to illuminate the Chromatte fabric (optional) for keying. Manufactured in two sizes, it is compatible with most digital and professional video camera lenses. The intensity of the light emitted by the LiteRing can be adjusted with the optional LiteRing controller. As a general rule, the LiteRing should be set to medium power and adjusted as needed depending on the distance and keying device to achieve optimal results. This is a LiteRing ONLY. This item is available as part of several different kits, which include the power controller, Chromatte or Chromaflex backgrounds in various sizes and lens adaptor rings.
