In this exhibit visitors experience how a bluescreen works by acting in front of it while being filmed. The result is immediately shown on the TV.
Bluescreen, also known as chroma key, is a term used in filmmaking to describe the technique that allows people and/or objects to appear in imaginary situations. This is often used in moviemaking but also in applications as the weather forecast.
This technique uses an evenly lit and single colored (blue or green) background. Through editing and combining of different video inputs the result will be as shown on TV.
