Reflecmedia’s Chromatte fabric is designed to work in conjunction with a LiteRing. The LiteRing features Light Emitting Diodes (LEDs) 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.
The LiteRing connects to the camera with a specially designed adapter ring, similar to those used for matte box mounting, which is attached to the inner thread of the lens. The LiteRing is then placed on to the adapter and simply locked with a single screw. This enables users to quickly release the LiteRing in between shots, or change from a green to a blue ring based upon their chosen keying color.
We have taken the blue or green color away from the fabric and completely removed the need to separately light the background. The ability to change the background color in seconds cannot be achieved any quicker – no need to hang a different drape or repaint the studio walls! Tungsten, HMI and Fluorescent lights can be large in size, expensive to power and uncomfortable to work under. Typically you require thousands of watts to light absorbent chroma key fabrics, whereas the LiteRing’s 10 watts output provides all the light required by Chromatte.
By relocating the color and the light into one camera-mounted device, we have significantly reduced the set-up time and overcome many of the difficulties associated with conventional chroma key.
The LiteRing comes with both green and blue LED’s, and is available in three sizes to fit different size cameras. Each size of ring has a series of adapters to ensure maximum compatibility with camera lens sizes. Further custom adapters and fixing mechanisms are available.
