For the sake of sanity, the brain and the eyes keep things simple. But take away the sense of sight and suddenly things are not so simple.

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.

It would be wrong to say that the city of Berlin is not regulated. What I think is more interesting is to what extent a city creates a sort of safe haven for its users, so that people feel confident that the city works on their behalf.

I don't know a single collector or museum director who says: 'Oh, he's on a list, so I think I'll buy something of his.' The people who buy my art put a little more thought into it than that.

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.

I do not think making art alone makes it any better than making it with a team of people.

I always try to make work that activates the viewer to be a co-producer of our shared reality.
