As far as the surface is concerned - oil on canvas, conventionally applied - my pictures have little to do with the original photograph. They are totally painting (whatever that may mean). On the other hand, they are so like the photograph that the thing that distinguished the photograph from all other pictures remains intact.

Weeks go by, and I dont paint until finally I cant stand it any longer. I get fed up. I almost dont want to talk about it, because I dont want to become self-conscious about it, but perhaps I create these little crises as a kind of a secret strategy to push myself.

Photography has almost no reality; it is almost a hundred per cent picture. And painting always has reality: you can touch the paint; it has presence; but it always yields a picture - no matter whether good or bad. That's all the theory. It's no good. I once took some small photographs and then smeared them with paint. That partly resolved the problem, and it's really good - better than anything I could ever say on the subject.

There is sorrow, but I hope one can see that it is sorrow for the people who died so young and so crazy, for nothing. I have respect for them, but also for their wishes, or for the power of their wishes. Because they tried to change the stupid things in the world.

I believe that he knew more what he was doing. I might be absolutely wrong about this, but that was my impression.

There was no special event that made me decide. I had collected some photos and the idea was in the back of my mind for a long time. It was growing and growing, so finally I said, 'I must paint this.' I come from East Germany and am not a Marxist, so of course at the time I had no sympathy for the ideas, or for the ideology that these people represented. I couldn't understand, but I was still impressed. Like everyone, I was touched. It was an exceptional moment for Germany.

I believe that art has a kind of rightness, as in music, when we hear whether or not a note is false
