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

Photographs have a relevance for things that cannot be said.

I myself have already spent a third of my life in Germany, first in Cologne and then, since 1994, in Berlin.

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.

Every city is always changing, on its own trajectory.

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.

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