HoloSet is a revolutionary approach to chroma keying developed in collaboration with researchers at the BBC. The HoloRing optical emitter was placed on a camera lens. HoloSet’s specially tuns retro-reflective background material would appear gray to the naked eye but a camera fitted with the HoloRing would see vibrant blue light waves reflected off the background. HoloSet eliminates artifacts like chroma-spill and tell-tale color ‘fringes’ around talent, it even works with scenes lit only by candlelight. HoloSet won three “Best of Show” awards at NAB and the technology remains on the market today.
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.
When the directional light from the Global Streams Holoset lens-mounted blue light 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 background. Due to the number of glass beads within the fabric, the cameraand 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 color through a retro-reflective process Chromate 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.
