• Balancing Cameras for Keying
• The image from each camera will need to be
  registering the background at the same brightness
  and saturation
• This is achieved by balancing the CCU settings
  and the keyer settings so camera switching will
  not result in inconsistent key quality

16

• Virtual Set
• Can be a simple colour splash background
• Or can represent a real studio space
• The cameras must be locked off to prevent the
  background floating
• When representing a real space, the background
  angles must match the camera angles
