If you are working with performers, it’s a good idea to use green screens only if you have to, or if the green screen forms components of a scene that actors won’t be interacting with. “It's not easy to act opposite green,” Bernstein explains. It can be difficult for talent to work together with the pieces of the scene if too many of them are represented by abstract green colors and objects. However, if the shoot requires it, make sure to brief the actors.
