I didn’t use any lights. It’s funny, because sometimes I talk to other cinematographers and they say, ‘Oh my God, Terry doesn’t let you use lights,’ but it’s not that he doesn’t let me — I don’t want to use them. On Tree of Life we really tried to do combinations of scenes with light and scenes without, and when you add movie lights they doesn’t have the complexity of natural light. You’re putting one light that has one tone and one color through some diffusion, and it doesn’t have the complexity of natural light coming in through the window from a blue sky and clouds bouncing green off the grass. Some would call that kind of light imperfect, but it’s more accurate to call it more complex. That complexity of natural light and the way it hits the face is amazing, and when you start to go that way it’s hard to go back and light [things artificially]. The less you use artificial light, the more you want to avoid it, because the scenes feel weak or weird or fake. Often we would be inside a house and it would be cloudy and we would know that we’d probably have to rewrite the scene and shoot it outside or come back another day, but that would be better than the option of lighting the scene and not liking it.
