Blog Post #146: Open Framing!
Open framing takes place when the elements within a shot composition are not positioned for optimum clarity. It is often seen in documentaries, conveying a greater sense of realism as opposed to closed framing where the elements of a shot appear more deliberately arranged. Open framing also provokes a lower emotional response and usually compels the viewer to wander over the frame.
These examples of open framing are from each of the films directed by George Lucas, who's referenced the technique in several DVD commentaries. It's one of the most distinctive aspects of Lucas' visual design strategy and a source of endless fascination to me.
