I don't mistrust reality, of which I know next to nothing. I mistrust the picture of reality conveyed to us by our senses, which is imperfect and circumscribed.

Talk about painting: there's no point. By conveying a thing through the medium of language, you change it. You construct qualities that can be said, and you leave out the ones that can't be said but are always the most important.

A lot of different things had to come together over the years, accumulated experiences of a general and personal nature, before the idea and the decision were developed and then carried out.

I believe that the quintessential task of every painter in any time has been to concentrate on the essential.

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.

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.

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.
