Getting a good even color behind the talent
is the first step in green screen, this usually requires
a chromakey backdrop in the form of cloth or paint. Some
green screen paint can be picked up at hardware stores or
lighting places like Studio Depot (Burbank, Ca), blue cloth
can also be found many places. Some companies sell green
screen pop up green screen backdrops which travel easily
and popup like a windshield shade.
Another alternative is
Chromatte,
a unique retroreflective material which is gray to the eye,
requires little or no light, and casts no spill on the talent
because the material is gray to the naked eye. But to the
camera it sees it as a perfect blue or green. This is because
of the
Litering,
a ring of LEDs around the lens which casts blue or green
light onto the Chromatte material. Chromatte is also very
portable in the form of a
Chromaflex,
a 7x7 popup which folds down into a 3 foot hoop. Chromatte
is superior to Green Screen in many ways.
