How Green Screen Studio Is Used In Cinema

By Trevor Weir


Green screen studio technology is a method that is used in filming and photography. Filmmakers and photographers use this to create visual effects that enhance the picture or create imagery that is completely new. This type of technology is also known as chroma key technology.

This use of technology initially started off using a blue screen in the background and now the standard format is to use green. The colours chosen is based how contrasting it is to the tones in the human skin. Over time, green just proved to be the more effective option in creating enhanced visuals especially when the filming is done outdoors.

Originally, green screen studio was used on television for weather reports. The results that it achieved were very impressive so filmmakers and photographers decided to incorporate it into their work.

Creating really good visual effects used to be quite a complex process and very time consuming. The previous method of creating similar effects was known as 'travelling matte'. There were several pioneers in this field namely RKO Radio Pictures. With new technologies, both in the computing and the photography world has made the task a lot simpler and quicker to achieve better results. Computers now do most of the work.

A lot of the improvement that we see in modern films is a result of the massive technological advances that have been made. Very high quality images are made just by the use of professional cameras. Nowadays, some films are made using completely computer-generated images.

In most of filmmaking today a green screen studio is used to film the takes and then scenery is added on later. This has huge benefits, as the actors are not required to leave the studio to be filmed at a particular location. Two actors who are in one scene do not need to be acting out their part in one frame either so it gives the whole filming process a lot more flexibility.
