People gather in two different basic ways. Fixed focus. Multiple focus. In the fixed focus relationship the audience and the performers are locked together within a clearly defined limit, like TV in a bar, the math professor at the blackboard, or a cock fight. The event is fixed between limits. The TV camera moves to keep the football “on camera.” The professor will not write on the floor. The cocks will not be let out of the pit. The Stratford, Ontario theatre, the San Francisco Opera House, the Washington Arena Stage, and your local Loew's are all fixed focus.
