Chromatte is a fabric designed specifically
for use as a background for chroma key production. Unlike conventional
chroma key fabrics that are usually blue or green in colour, Chromatte
is grey to the eye in ambient light. The fabric contains millions
of tiny glass beads that act as reflectors, returning any light
shone on them back to it's source.

Chromatte
When
the directional light from Reflecmedia's lens-mounted LiteRing hits
the Chromatte fabric, it is returned on the same path and back into
the camera lens - as such the camera sees the otherwise grey fabric
as a perfectly even blue or green background. Due to the number
of glass beads within the fabric, the camera and LiteRing are free
to move and can work at acute angles to the fabric. In the extreme
you can screw the fabric into a ball and still key against it!
By generating the background colour through a retro-reflective process
Chromatte offers unrivalled benefits;
Lighting
Conventional fabrics require significant lighting to create an even
colour background, whereas the only light required to light Chromatte
comes from the LiteRing. This also means that any spill from unwanted
light is eradicated and that chroma key can now be used in low-lit
scenes and sets.
Space
By removing the need for additional lighting, Chromatte takes chroma
key out of the studio and into any controlled lighting environment
- an office, meeting room or garage can be a chroma key location
in minutes.
Time
For even an experienced lighting engineer it can take hours to light
a chroma key set. In many instances, the time involved and the difficulties
of achieving high quality results have prohibited the use of chroma
key in lower budget and time-sensitive productions.
Chromatte is supplied in a range of standard size or custom produced
studio drapes, where the fabric is backed with a black light-proof
drape and hemmed with eyelets across the top for easy hanging from
studio tracking or rail.
