With the power of green screen and keying you can do almost anything. But how does this all work?
Green screen technology is what we in the media industry call Chroma keying. That is picking a single colour, in this case green, and making that colours value transparent therefore removing it, allowing another image to show through.
But why Green? It is used because of contrast. In order to remove one area from the rest of the background, the colour must stand out and be distinctively different. Blue also works, however it is a commonly worn so green is a better option. After all we don’t want to pierce a hole through the subject or make them invisible all together.
