I believe I am looking for rightness. My work has so much to do with reality that I wanted to have a corresponding rightness. That excludes painting in imitation. In nature everything is always right: the structure is right, the proportions are good, the colours fit the forms. If you imitate that in painting, it becomes false.

When I paint from a photograph, conscious thinking is eliminated. I don't know what I am doing. My work is far closer to the Informel than to any kind of 'realism'. The photograph has an abstraction of its own, which is not easy to see through.

Contact with like-minded painters - a group means a great deal to me: nothing comes in isolation. We have worked out our ideas largely by talking them through. Shutting myself away in the country, for instance, would do nothing for me. One depends on one's surroundings. And so the exchange with other artists - and especially the collaboration with Lueg and Polke - matters a lot to me: it is part of the input that I need.

The reason these paintings are destined for New York is not because I am disappointed about a lack of German interest, but because MoMA asked me, and because I consider it to be the best museum in the world.

Maybe we didn't even have a chance. The message of American Pop Art was so powerful and so optimistic. But it was also very limited, and that led us to believe that we could somehow distance ourselves from it and communicate a different intention.

I find the Romantic period extraordinarily interesting. My landscapes have connections with Romanticism: at times I feel a real desire for, an attraction to, this period, and some of my pictures are a homage to Caspar David Friedrich.

I am ridiculously old-fashioned.
