Realization of green picking

In order to achieve the purpose of greening out, actors and props are required not to use green during filming. The green background requires uniform light and no shadows or color differences. In order to achieve the purpose of changing the background, in addition to green-keying, we often "blue-key", that is, shooting with a blue background.

Whether it is green or blue, it is generally done in a studio, because only a studio can arrange the light as evenly as possible. In the industry, this kind of studio specially used for green picking is called a "green box".
