Green Screens

In school time our class has been making green screens. A green screen is like a film making set with a green sheet behind the scene. What it does is it makes you look like you are in front of like something you really aren't. We did our screen on Myst like we were in the game. We had a script and it had what we said on it. We didn't have a green screen we had a white screen which was a wall. Everybody has seen a green screen before like on TV how they do the weather report. There in front of a green screen. Have you noticed why they don't wear green? Because if they wear green {the same as the wall} they look like they are in visible. Green screens are heaps of fun and are a good web 2.0 tool.
