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.

If the abstract paintings show my reality, then the landscapes and still-lifes show my yearning.

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.

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.

I wanted to say something different: the pictures are also a leave-taking, in several respects. Factually: these specific persons are dead; as a general statement, death is leave-taking. And then ideologically: a leave-taking from a specific doctrine of salvation and, beyond that, from the illusion that unacceptable circumstances of life can be changed by this conventional expedient of violent struggle.

I was a student, and as such you generally rely on prior models of how to make art, but these were not satisfying. Then I discovered in photos what had been missing in paintings; namely that they make a terrific variety of statements and have great substance. That is what I wanted to convey to paintings and apply to it.

The paint for the grey paintings was mixed beforehand and then applied with different implements - sometimes a roller, sometimes a brush. It was only after painting them that I sometimes felt that the grey was not yet satisfactory and that another layer of paint was needed.
