Green Screen Research:

Green Screen Research:


Green screen is used in films, television and video sequences It is often used when the film company or television company are on a low budget. The effect us used with actors and actresses in front of a green screen. This then allows the location and acting to be shot separately. 


History:


Green screen was known many years ago and it was recognised to be one of the most inventive and imaginative techniques of creating effects. In the year of 1970, the colour blue in chroma key was finally transformed to the colour green. In the same year the green screen became famous when it cam to video and film editing. It was aso used in photography. 


Green screening is mostly used in films and television but it is also used in video games. It is used because the top layer of colour can be made transparent so that another image can be seen behind it. This is useful because it can be made to look like actors are somewhere else. For example a moving background can be put behind actors to make them look like they are located somewhere else.

Use of green screen

Fast and Furious 4:

In Fast and Furious 4 there is a scene where Dom is dangling someone out of a window. The background is green screened. This is because it would be dangerous to hang someone from a high ledge. Also it would have been expensive to find a exotic location with a hotel. So the director took the decision to use green screen in the scene. Also the background can be a still image to enhance the scene.
