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.
