A visual effects process that began in blockbuster films can be a starting point for rich cross-curricular topics
Have you ever wanted to swim with sharks but were too scared? Or, have you ever wanted to go to the Moon but haven’t had the call from NASA yet? Now you can! It’s all very simple and uses a technology called green screening.
What is green screening?
You’ve seen green screening in action even if you didn’t realised it – when Harry Potter flies on his broom, when the Starship Enterprise visits other worlds, or even when you last watched the weather forecast. The way that it works is that the actors stand in front of a green screen and act as if they are on a mountain or in a jungle. This video footage is then put into a computer and the software replaces the green colour with another background.
