Just finished reading the book Annie Leibovitz At Work, and on page 207, this is what she said...
"Digital gives a more honest view of how things actually look, and with the advent of all these possibilities, I still want the pictures to look like they're real. Whatever camera helps me do that is the camera I'm going to use. I'm not nostalgic about cameras. When I talk about how important the camera is to me, I mean the idea of the camera. What photography does. I'm not into it because of the equipment, and I'm not concerned with the things that concern more technically acute people. I want to use whatever helps me take a picture in all kinds of light with faster speed and fewer problems. I changed my 35mm digital camera four times in one year. As soon as I hear there's a better one out, I'll try it."
