If we are to change our world view, images have to change.

If you see the world as beautiful, thrilling and mysterious, as I think I do, then you feel quite alive.

I think I’m greedy, but I’m not greedy for money – I think that can be a burden – I’m greedy for an exciting life. I want it to be exciting all the time, and I get it, actually. On the other hand, I can find excitement, I admit, in raindrops falling on a puddle and a lot of people wouldn’t. I intend to have it exciting until the day I fall over.

I think probably something big can be done with cameras, I'm not saying, er, I'm saying chemical photography's finished, that means you can't have a Cartier Bresson again, you need never believe pictures.

About shadows: do we see shadows? Loads of people don't. A camera will notice a shadow, but how many people have got a shadow in front of them when they take a picture and don't notice it, and then they see it in the photograph because the photograph will catch the shadow.

I have got an iPad, what a joy! Van Gogh would have loved it, and he could have written his letters on it as well.

Of course you can still paint landscape - it's not been worn out.
