Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Primatte is a high-end chroma key technology used in motion picture, television and photographic host applications to remove solid colored backgrounds (greenscreen or bluescreen usually) and replace them with transparency to facilitate ‘background replacement'. It uses a unique algorithm based on three multi-faceted polyhedrons floating in RGB colorspace that are used to isolate color regions in the foreground image. Primatte is often referred to as a compositing technology and is usually used as a plug-in for host products such as Adobe After Effects, Adobe Photoshop, Autodesk Media and Entertainment Inferno or Flame, Eyeon Fusion and several other compositing and editing software packages. Primatte is usually activated on a foreground image with a person or other foreground object filmed or digitized against a solid colored background or backing screen; usually a bluescreen or a greenscreen.
