How
a green screen work
A green screen makes it possible to film all your scenes in one location. It just seems like you are somewhere else. This of course requires a good film editor who can make it look as real as possible.
A green screen is literally a green screen that makes it possible to adjust the background as desired when filming. This way you can film a scene in New York and Paris in one hour. The biggest advantages of a green screen are the time and money you save, in addition to the fact that it often has a funny effect because of all the creative things you can do with it. A disadvantage is that without proper editing and preparation, a green screen film quickly appears fake.
