I tried to make a kind of environment in the room where I lived in Kentish Town and to make a film within it There were pieces of paper and screwed up transparent gels hanging from the ceiling it was quite dense in some parts I wandered through it with a camera and then other parts were filmed on the rooftop at St Martins I think I was just very much trying to find my way in a whole new area of work I remember it involved a lot of refilming which was the part I liked The process was very fluid similar to painting I got quite interested in the specks of dust and dirt on the film and the refilming gave me a chance to look at that more closely Probably the thing that attracted me to film was the light the kind of floating quality you can get images suspended in light
