Focus' falls into two distinct sections, and again employs a loop structure.
In the first section, the camera/operator penetrates through a confined space of art objects (which include a beautiful perspex sculpture that swings gently and occasionally into the left area of the frame) into a kitchen and the barred garden view beyond. The repetition of this emphatically mechanistic zoom shot is then paralleled in the second section by a movement from soft to sharp focus on a girl's self-conscious face. The effect is similar to that in 'Hall'; what is important is an awareness of how these simple, elemental cinematic techniques can manipulate, as they transfigure, our conception of a predetermined 'reality'.
