Post production techniques for video part II / How to work with chroma key color
Chroma key – commonly referred to as blue screen or green screen – is the technique for combining two images, in which the colored background from one image is removed (or made transparent).
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 color, in ambient light Chromatte is grey to the eye. The fabric contains millions of tiny glass beads that act as reflectors: when any light - such as the directional light from Reflecmedia's lens-mounted LiteRing – hits the fabric, it is returned on the same path back into the camera's lens. This retro-reflective process means the camera 'sees' the apparently grey fabric as a perfectly even blue or green background.
