The camera was pointed at right angles across a busy park pathway connecting one part of the city to another. On the other side of the path are many trees receding into the distance. Many people move through the picture, both on and off the pathway. One frame was taken each time a person on the pathway moved into the picture and one frame was taken again as they moved out. The procedure was repeated over a period of three days with filming beginning at dawn and ending at dusk. Two of the days were sunny and the other was very stormy. The speed at which people, clouds and shadows move in the film is directly related to the flow of people through the park.

This is not so much a film about a park, or a record of the people passing through the park. Here the camera is not a passive observer, nor is it used as a surveillance device. Rather, in Park Film, the camera, like the passers by who trigger its shutter, is an active participant in the interaction between a park and the city, which surrounds it. The film is the result of that interaction.
