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.

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.

Photographs have a relevance for things that cannot be said.

In the past Berlin was much more radical and extreme and now it's becoming much more of a conventional European city.

Having an experience is taking part in the world. Taking part in the world is really about sharing responsibility.

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

I think an artist has the potential to investigate both form and content within one activity, to show that there can be coherence between form and values in our society, as in thinking about a city and building one.
