I don't pretend to be an intellectual or a philosopher. I just look.

The maximum, that is what has always interested me.

I don't like captions. I prefer people to look at my pictures and invent their own stories.

My work has no theme. I don't care if my photographs get published, and I have no interest in the news. But the invasion of Prague was not news, it was my life.

When I photograph, I do not think much. If you looked at my contacts you would ask yourself: "What is this guy doing?" But I keep working with my contacts and with my prints, I look at them all the time. I believe that the result of this work stays in me and at the moment of photographing it comes out, without my thinking of it.

Sometimes I photograph without looking through the viewfinder. I have mastered that well enough, it is almost as if I were looking through it.

My photographs are proof of what happened. When I go to Russia, sometimes I meet ex-soldiers... They say, 'We came to liberate you....' I say: 'Listen, I think it was quite different. I saw people being killed.' They say: 'No. We never... no shooting. No. No.' So I can show them my Prague 1968 photographs and say, 'Listen, these are my pictures. I was there.' And they have to believe me.
