Most movies. news reporters and any even some adverts use green screens to enable them to use a large amount of effects for the users to see. An example is that an actor could be appearing to be falling off a tall building, generated by the green screen, when in reality they are actually on the ground acting as if they were falling. This will save the company a lot of money. They can also edit the characters to look smaller, bigger, better looking, uglier etc.
Another example of people using green screens is during the weather section of the news where the weatherman uses a green screen to display the map of the country with the changing weather effects. The weather reporter cannot see the green screen or the map but can still tell the weather to the viewers. This is the main reason why the new reporter will never wear green clothes as they will blend in with the green screen.
A lot of movies try to save money by using green screens which to create their special effects.A great number of movies are using them nowadays but the viewers don't realise it.
By using a green screen it can help to make a scene look and better for example if filming an outside shot and the weather is dark and cloudy, a green screen could be used instead to if the director wanted a bright sunny shot.
