July 14 Happy Camp venues are all green. What is this?

Picking green refers to shooting with green as the background when shooting or taking pictures, and in post-production, using the "color key" of stunt machine to pick out the green background and replace it with other more ideal backgrounds, so as to make actors and props look like shooting in other more ideal backgrounds. In order to achieve the purpose of digging green, actors and props are required not to use green when shooting. Green background requires uniform light, no shadow and color difference. In order to change the background, in addition to digging green, it is often "digging blue", that is, shooting with a blue background. Whether cutting green or blue is usually done in the studio, because only the studio can arrange the light as evenly as possible. This kind of studio dedicated to digging green is called "green box" in the industry.
