The notion of a line which divides the land from the sea is a notion of convenience which is only valid in certain circumstances. If there is a line at all, it only exists for a second or so, and is never repeated again. This film was shot on this imaginary line, but the leading or trailing edge of the wave is never represented. The shore line is replaced by a frame line which divides each one-second "take" from its neighbour. The frame is either filled with water or littered with stones and sand exposed after the wave has receded. The image on the screen, the organic rhythm of the waves, is not destroyed by the violence of the structures imposed upon it. Nature emerges uninhibited, revealing yet further complexities of shape and form. The illusory shore line remains invisible, trapped on celluloid, hidden by the mechanics of the projector, and de-materialised by the illusion of cinematographic movement.
