The camera films a park landscape through the flat mirror
blades of a small windmill. The film was shot in one continuous
400 foot take. The camera looks through the blades of the windmill,
recording either what is behind or in front of the windmill blades.
A rhythm determined by the speed and direction of the wind.
This film is one of a series of films (Wind Vane, Anemometer,
Tree, Park, Estuary etc.) which uses an element present
within the frame as a feedback device to control an aspect
of the recording process. In this case it is the wind moving
the leaves on the trees within the frame which also causes
the windmill to rotate like a secondary shutter in front of
the camera. This rotation of the mirrored windmill blades causes
the image on the screen to alternate between the space in front
of the camera, seen intermittently through the blades, and
the space behind the camera, reflected in the blades. When
the windmill reaches a particular speed, a third space is also
created as the deep space of the picture plane fragments and
becomes a two dimensional abstract surface of colour and light.
The duration of this film was limited by the length of a roll
of unexposed film stock. The shape of the film, however, was
entirely dependent on the strength and direction of the wind.
"In Windmill III, a mirrored windmill set before
the camera divides the image into three distinct areas: the space
in front of the windmill, the space occupied by the windmill
itself, and the space behind the camera that is reflected in
the blades. When the windmill turns slowly, the blades smoothly
displace—or "wipe"—the front landscape
with the reflected images. As the wind picks up, the windmill
rotates faster and the reflected images blur, creating painterly
smears across the foreground. By sectioning linear perspective, Windmill
III not only challenges the standard presentation of space,
it also highlights what is normally unseen - the space behind
