I recently came across Steven Spielberg's interview to WIRED magazine, were he talks about digital vs. film in cinematography. Here is the quote (full version is here):
"Now the thing I'm most saddened by is the constant talk about the photochemical process becoming a thing of Thomas Edison's past. There's a magic about chemistry and film. Sure, a digital shot is steady. It doesn't have to ride through the gate of a projector. And, sure, it's as clean as the OR in a major hospital. That's exactly what's wrong with it. Film has a molecular structure called grain; even a still of just a flower in a vase has life because of the grain, because of the molecules in the film. Especially if you sit in the first five rows of any movie theater, you know what I'm talking about. The screen is alive. The screen is always alive with chaos and excitement, and that will certainly be gone when we convert to a digital camera and a digital projector. I was one of the first people to use digital technology to enhance my films, but I'm going to be the last person to use digital technology to shoot my movies."
