'I maintain that the most interesting things are invisible. I'm interested in how things feel rather that what they look like. Like if someone you love walks out on you, you're destroyed and you cry. So if you see a woman crying, well anyone could photograph that, but why is she crying?...I've always had to work around what photography does best, which is to duplicate the obvious reality, the reality of facts. I feel that many photographers don't question what they look at, they simply reproduce it.'
