"Sufficient time is rarely taken to study light. It is as important as the lines the actors speak, or the direction given to them. It is an integral part of the story and that is why such close coordination is needed between director and cinematographer. Light is a treasure chest: once properly understood, it can bring another dimension to the medium… As I worked with Ingmar, I learned how to express in light the words in the script, and make it reflect the nuances of the drama. Light became a passion which has dominated my life."
