I shot a lot of commercials and sometimes I enjoy the commercial shooting and sometimes I really hate it, but in thirty seconds or one minute, you can make some remarkable work shooting in one or two or three days.

I encourage film students who are interested in cinematography to study sculpture, paintings, music, writing and other arts. Filmmaking consists of all the arts combined. Students are always asking me for advice, and I tell them that they have to be enthusiastic, because it's hard work. The only way to enjoy it is to be totally immersed. If you don't get involved on that level, it could be a very miserable job. I only have one regret about my career: I'm sorry that we are not making silent movies any more. That is the purest art form I can imagine.

When I was in Hungary in December I was looking at student films and I could not tell which ones were shot on film and which ones were shot digitally. I think that is because the filmmakers in Europe go to four years of film school and learn the techniques.

I should mention Vittorio Storaro, who was Bernardo Bertolucci's cinematographer. You watch those films and they are exceptional.

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.

With television, it's difficult to do some things. You have to shoot so many minutes a day, so you always have to be prepared or you won't be able to complete the number of pages that you have scheduled for that day.

I think that the audience should not be able to tell if it is real or not real - it should be an enhanced version of reality, or an artistic view of reality, that captures not only what is physically there, but what is not visible - the mood.
