Open framing implies that the world of the film is a momentary glimpse into a specific part of said world, hence the reason it is used heavily in documentaries so as to give the audience perspective and a greater sense of scale. A film I have chosen to illustrate the open use of framing is Children of Men (2006) directed by Alfonso Cuarón. The shot, shown right, clearly exibits an outside world to give the viewer the feeling that more the world of the film is a momentary frame around an ongoing reality, which is the case in Children of Men.
