In Slumdog Millionaire when you are immersed in the point of view of children in the slum and the bustle of the city, the handheld camerawork is amazing. A handheld camera is perfect for establishing point-of-view and for instilling the feeling that you are there.

I was really fortunate from the time I arrived in Hollywood to work with some of the greatest directors from the beginning. I worked with Robert Altman, John Boorman, and of course Steven Spielberg, Michael Cimino, Brian De Palma ... I couldn't pick one of them; they were all different, but they are all so talented.

Using film was so much easier than the digital technology of today. But digital is still at the beginning of what it can be and they'll be fixing all those problems. It's just too complicated - negatives, tinting, flashing - it's a whole new system that takes a lot of time. Of course, it's not as physical. Even the editing. You used to feed a piece of celluloid into an editor. [Digital] is not expensive and that is an advantage, but I must say that I don't love it.

Even in manipulating the images, I would like to do my dailies in a digital way because you can do so many things in that stage that I cannot do in real photography.

When I first came to America there still was Look Magazine and LIFE Magazine, and the photography in those magazines was amazing to look at. They had the best portraits, and their news photography.

I love the Dutch impressionists - Vermeer, Rembrandt. What they were able to do with light was astonishing. As for photographers, I think mostly of the Hungarians: Robert Capa, Laszlo Moholy-Nagy, Jozsef Pesci. In fact, I have one of his photographs hanging in my house.

Kubrick was one of those directors who actually did practically everything in his movies. He actually directed, photographed, wrote, lit, edited - everything. A few people can be like that.
