Quote:
"Because the space within the frame contains little to hold our interest, our attention is drawn to the source of the sounds emanating from off-screen locations. By placing so much of the content of the film in the off-screen sound and by using shots of prolonged durations, Epp suggests the notion of absence that resides in photographic representation."
