Green screen technology refers to the process of mixing two images together. In this technique, the color of one image is removed to reveal another image behind it. Green is often used as a background as compared to other colors because image sensors in digital video cameras are most sensitive to this color. Therefore, the green camera channel contains the least "noise" and can produce the cleanest mask. Additionally, less light is required to illuminate green because of the higher sensitivity to the color in image sensors. The technology produces results in the form of effects you see in everything from the weather forecast to blockbuster movies.
