Chromatte fabric is designed to work in conjunction with a LiteRing. The LiteRing features Light Emitting Diodes (LEDs) that are arranged in a circular casing that is positioned in front of the camera lens. This provides all the light required to illuminate the Chromatte background for chroma key production.
LiteRings are available in a new dual colour format in small and medium sizes and also in a seperate green and blue format in three sizes to fit different size lenses. Each size has a series of adapters to ensure maximum compatibility. These specially designed adapter rings simply screw into the filter thread on the front of the lens and then the LiteRing is placed on to the adapter and locked with a single screw, significantly reducing the set-up time associated with conventional chroma key.
Because not all lenses are designed with the filter thread required to attach the LiteRing to the lens, Reflecmedia has added additional adapters to their range of products to enable the user to attach the LiteRing to lenses such as film primes and HD wide angles.
