Green Screen

The use of a green or blue background (also known as chroma keying) is well known for use with special effects – many, in fact the majority,  of films you see nowadays have been made with actors playing their parts against a blue background, and the other details are added in post processing. Actually green tends to be used more for stills, and blue for films – any blue colour reflected into the shadows tends to look more like a reflection of the sky, while green appears less often in people’s clothes

How does it work?

Photos are taken normally against a green background and sent to the computer as normal. It is then processed by special software that automatically removes the green background and leaves a transparent area in it’s place. It then layers the photo on top of a chosen background, perhaps adding shadows to make it more realistic and, where applicable, another layer can be added on top. The finished “sandwich” can then be processed by normal photographic software.

This makes it possible to create a photograph in the studio that would be impractical in any other way. For backgrounds, we can either use some from our own library, select from one of the many stock libraries, or take one especially for the purpose. The possibilities are endless.
