Chroma Key
Turn on the Chroma Key, a color from the key source will be removed, revealing another background
image behind it. Chroma Key is usually used for virtual studio, such as weather broadcasts, where the
meteorologist appears to be standing in front of a large map. In the studio the presenter is actually
standing in front of a blue or green background.
