This is a neat piece on how visual composition is used in film. Isn't it great that we live in a world in which someone can produce a sort of short-form documentary slash illustrated lecture and make it available to anyone interested in the creative process behind filmmaking? I wish the world were as great in other ways as it is in its provision of technology for the privileged. (That last sentence almost reads like parody to me, but it's entirely true.)
