When museums are left with so little money that their future is in the hands of private donors, then they are unable to develop their own signatures by collecting themselves. On the other hand, though, I think we should also celebrate the fact that there is a lot of art that lives outside of, or on the outskirts of, the art market - and it is doing quite well.

The viewer brings something individual to the experience of any artwork.

I want to expose and evaluate the fact that the seeing and sensing process is a system that should not be taken for granted as natural - it's a cultivated means of reality production that, as a system, can be negotiated and changed.

I see the artist as a participant, a co-producer of reality.

By bringing Little Sun to Tate Modern and the London Olympics, I hope to realise an art project for those who typically have no access to global events of this scale.

Light has an evident, functional and aesthetic impact on our lives.

I can use the camera to make a place or landscape; the camera to a greater extent projects rather than takes in or reproduces. The camera, or, rather, the eye, produces the impression of the place: I as a photographer am not passively taking in; I am active as a subject generating the object.
