Litering

The Virtual Set is fast becoming a common means of television and film production. A Virtual Set uses chromakeying to create a set or stage that isn't real, and in some cases could not be. An actor or talent stands in front of or on a Chromatte stage and a piece of hardware or software called a chromakeyer like an Ultimatte removes the color and replaces it with an image generated by a computer. This is possible because of the Litering from Reflecmedia a ring of LEDs that goes onto the camera lens. The Litering shines blue or green light (depending on the Litering color) onto the Chromatte. The light from Litering gets returned only back to the camera lens where the Litering is mounted. This is because the Chromatte only reflects light back at it's source, so the Litering, mounted on the camera lens, only sends light from the Litering back to the camera.

Chromatte

A new means of chromakeying, Chromatte, is a chromakeying solution from Reflecmedia. It works by placing a ring of LEDs called a Litering around the camera lens. The LEDs shine blue or green light from the Litering onto the Chromatte. The Chromatte is made up of millions of microscopic glass beads which are hemispherically coated in aluminum. This makes it covered in literally millions of tiny dish shaped mirrors. The net optical result is that any light shined onto the Chromatte is only reflected back at it's source. Because of the unique way that the Chromatte reflects light only back at it's source it can do a number of things that traditional chroma key techniques cannot. Chromatte can work in almost no light making it idea for virtual sets, because the color is generated by the LEDs and the Chromatte only sends like back to the camera so you can light your talent for the virtual set they are in. This also makes it so it has no spill since there are no bright lights reflecting the very color you are trying to key off the background and onto the talent's hair and shoulders.
