Green Screen Experiment

In lesson we were experimenting with the green screen. We wanted to produce a small sequence using the screen, so we could decided whether or not we wanted to use green screen in our final 2 minute opening scene. The technical term for green screen is 'chroma keying' a technique that merges two images or frames together in which a colour from one image is removed (or made transparent) revealing another image behind it. This is commonly used for weather forecasts where the presenter appears to be standing in front of a map, when it is actually a green screen.
