Chroma Key
In a chroma key two images are combined using a special
technique and a color from one image is removed,
revealing another image behind it. Chroma key is
commonly used for weather broadcasts, where the
meteorologist appears to be standing in front of a large
map. In the studio the presenter is standing in front of a
blue or green background. This technique is also referred
to as color keying, color-separation overlay, green screen,
or blue screen.
