green screen technology

Green screen technology, also known as chroma keying, is a visual effects technique used to replace the green background behind a subject with any other image or scene. During filming, the background is illuminated and shot against a uniformly green backdrop. Specialized software then identifies this green color and replaces it with a chosen environment, such as a scenic landscape or digital backdrop. This process allows filmmakers and videographers to create realistic settings and effects that would be difficult or impossible to film in person, making it a powerful tool for visual storytelling.
