Photography is such an important instrument in the education of our feelings and perception because of its duality. Photography represents the world we know, and suggests a world beyond what we can see. Creativity is the gap between perception and knowledge.

I was going round the world searching for an interesting place, when I realized that the place that I was in was already interesting.

Twentieth-century art has allowed me to see things in a cryptic way. I love the butterfly's wings, which disappear when folded and when open leave this brilliant, intense pronouncement of nature, 'Here I am.'

Of course, this is one of the really important things about art, that you can make more than you can understand at the moment the thing is being made. But the gap between what we recognize inside ourselves - our feelings- and our ability to trust ourselves and to trust exposing ourselves to those ideas, can be great.

The trust that develops from such a habit engenders risk, and you realise you're not as vulnerable as you thought. Once you become comfortable with being more truthful about who you are, the easier it is, the prouder you become. That's the way it unfolded for us.
