They are specific places I have discovered here and there when I am on the road to take photos. I go especially to take photos.

Painting pictures is simply the official, the daily work, the profession, and in the case of the watercolours I can sooner afford to follow my mood, my spirits.

I'm never really sure what that word means, but however inaccurately I use it, 'classical' was always my ideal, as long as I can remember, and something of that has always stayed with me, to this day. Of course, there were difficulties, because in comparison to my ideal, I didn't even come close.

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.

I first came up with the idea for the colour-chart pictures back in 1966, and my preoccupation with the topic culminated in 1974 with a painting that consisted of 4,096 colour fields. Initially I was attracted by the typical Pop Art aestheticism of using standard colour-sample cards; I preferred the unartistic, tasteful and secular illustration of the different tones to the paintings of Albers, Bill, Calderara, Lohse, etc.

Art is the pure realization of religious feeling, capacity for faith, longing for God. ... The ability to believe is our outstanding quality, and only art adequately translates it into reality. But when we assuage our need for faith with an ideology we court disaster.

The grey is certainly inspired by the photo-paintings, and, of course, it's related to the fact that I think grey is an important colour - the ideal colour for indifference, fence-sitting, keeping quiet, despair. In other words, for states of being and situations that affect one, and for which one would like to find a visual expression.
