Chroma key compositing and lighting adjustment system

An expandable system comprising:

• a back-wall;
• a first sidewall that extends from a first back-wall edge;
• a second side-wall that extends from a second back-wall edge, the second back-wall edge situated opposite to the first back-wall edge;
• a ceiling supported by the back-wall, first sidewall or second sidewall, wherein the first side-wall, back-wall, second side-wall and ceiling form a semi-enclosure about a subject area, a surface of the semi-enclosure comprising of a monochromatic color;
• a crown horizontal lighting module affixed to the ceiling, the crown lighting module containing a first plurality of light sources, the first plurality of light sources configured to direct light towards the surface of the semi-enclosure, the first plurality of light sources configured to be selectively dimmed, brightened or change color;
• an overhang lighting module affixed to the ceiling, the overhang lighting module containing a second plurality of light sources, the second plurality of light sources oriented towards the first subject area and the surface, the second plurality of light sources configured to be selectively dimmed, brightened or change color independently from the first plurality of light sources;
• and
• a processor configured to control the intensities of the first and second plurality of light sources such that a Chroma key balance is achieved between a subject in the first subject area and the surface.
