Green Screen Research

What is green screening?
Green screening is what people use in films and videos to create an effect or background to make it easier for the directors. The green screen is green because the color is not normally used in shots which they want to use, they shoot the video/clip in front of the green screen to then when it comes to editing they replace the green screen with a back choice to make it look like they've shot the film in that place. When it comes to choosing what material you’re going to use for your green screen, you need to think about the lighting, you need to make sure there is no reflection because that could mess up what you're then replacing the green screen with. The effect will not turn out as good as you wanted and expected. 

The history of green screening.
The idea of creating a fake image behind the raw footage has been around for a very long time. In 1930 the blue method was being used, when blue screening was around they'd shoot the back ground shoot first and then film the actor/actress in front of a blur screen and then just simply overlap the two when editing. As time went by film makers discovered that green was really a better color. In 1970, the color blue in green screens was finally transformed to the color green also green screen became famous when it came to video editing as well as photography.  Many film makers prefer to use the green screen since it permits less light.

Green screening is probably used in so many more films and programs that you think, they can look so realistic that you would never know that the raw footage and background are two separate parts. For example, when movies are set in big cities like New York or London, it's a lot of effort and time to get permits to shoot, making people who are around get out of the way to film, the back ground noise ect so green screen helps loads to then do two separate shots and the raw footage is shot in the studio with the technology to shoot the film correctly therefore the finished movie comes out perfectly and the audience would know no difference.
