This is a very nice interview with Christopher Doyle, the cinematographer made famous through his work with Wong Kar Wai.  In it he marks a distinction between asian approaches and western cinematography with its idea of the proscenium.  This sent me to wikipedia, where I learned that a “Proscenium theatre is a theater space whose primary feature is a large archway(the proscenium arch) at or near the front of the stage, through which the audience views the play.”   In contrast to this theatrical style, Doyle describes his approach as one of discovery.
