Watch Yes No Maybe Not - BFI Player

The film depicts the sea breaking against a timber break-water, juxtaposed with and superimposed upon smoke rising from the chimneys of Battersea Power Station. Although the images have been chosen for meanings and qualities they imply, the film resists narrative and theme - its impact comes through the way in which the images are transformed in the printing, mainly comprising certain kinds of positive-negative superimposition.
