Here is an example of Green Screening:
How do Green Screens work?
In movies and on television, actors walk and sometimes fly, through elaborate and fantastic landscapes that simply do not exist in the real world. All of this happens with the help of backdrops of brightly coloured fabric or paint, and a process called chroma keying, also referred to as a green screen due to the backdrops' colour, which is typically a vivid green.
Chroma keying allows media technicians to easily separate green screens and panels from the people standing in front of them and replace those backgrounds with pretty much anything:
Chroma keying is not just for backgrounds, it works with objects too. elaborate animated characters, such as the dragons in 'Game of Thrones', often have bright-green stand-ins that actors hold and interact with, but which the fully rendered animal replaces during editing.
Over decades, chroma key tech has become more sensitive and sophisticated. improved edge detection and the capability to separate even individual hair on foreground actors' head from a green background makes integrating live action with spectacular effects more seamless and realistic than ever.
Digital technology has also become cheaper and more accessible and chroma key is now within reach for anyone with a smartphone or tablet. Many different apps such Photoshop make is possible for the ordinary public to tweak and manipulate their own photos.
