The year is always correct, also the month, only the day can be another. But that occurs to me only in the moment of writing it down.

The desire to please is maligned, unfairly. There are many sides to it. First of all, pictures have to arouse interest before people will even look at them, and then they have to show something that holds that interst - and naturally they have to be presentable, just as a song has to be sung well, otherwise people run away. One mustn't underrate this quality, and I have always been delighted when my pieces have also appealed to the museum guards, the laymen.

Turning to the colour-classification methodology: The starting point are the four pure colours red, yellow, green and blue; their in-between shades and scales of brightness result in colour schemes containing 16, 64, 256 and 1,024 shades. More colours would be pointless because it wouldn't be possible to distinguish between them clearly.

Composition is a side issue. Its role in my selection of photographs is a negative one at best. By which I mean that the fascination of a photograph is not in its eccentric composition but in what it has to say: its information content. And, on the other hand, composition always also has its own fortuitous rightness.

I don't believe in the reality of painting, so I use different styles like clothes: it's a way to disguise myself.

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 see the bomber pictures as an anti-war statement... which they aren't - at all. Pictures like that don't do anything to combat war. They only show one tiny aspect of the subject of war - maybe only my own childish feelings of fear and fascination with war and with weapons of that kind.
