But it is also untrue that I have nothing specific in mind. As with my landscapes: I see countless landscapes, photograph barely 1 in 100,000, and paint barely 1 in 100 of those that I photograph. I am therefore seeking something quite specific; from this I conclude that I know what I want.

Everything has a reason, including the selection of the photos, which was not arbitrary but appropriate to the period, its highs and lows and my sense of them.

Grey. It makes no statement whatever; it evokes neither feelings nor associations: it is really neither visible nor invisible. Its inconspicuousness gives it the capacity to mediate, to make visible, in a positively illusionistic way, like a photograph. It has the capacity that no other colour has, to make 'nothing' visible.

That was a piece I did in 1963 with Konrad Lueg in a department store, in the furniture department. It was announced in some papers as an exhibition opening, but the people who came didn't know that it was to be a sort of Happening. I don't think it is quite right that it has become so famous anyhow. It was just a lot of fun, and the word itself, Capitalist Realism, hit just right. But it wasn't such a big deal.

I remember that I felt I had to avoid all these sensational photos, the hanged woman, the man who shot himself, and so forth. I collected a great deal of material, including a number of banal, irrelevant photos, and then in the course of my work I came back to the very pictures I had actually wanted to avoid, which summed up the various stories.

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.

Family photos, pictures of groups, those are truely wonderful. And they are just as good as the old masters, just as rich and just as beautifully composed (what does that mean anyway).
