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.

The biggest lesson in photography is that from negative we make a positive

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

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.

The maximum, that is what has always interested me.

I am not interested in repetition. I don't want to reach the point from where I wouldn't know how to go further. It's good to set limits for oneself, but there comes a moment when we must destroy what we have constructed.

I have never had any hero in my life or in photography. I just travel, I look and everything influences me. Everything influences me. I am quite different now than I was 40 years ago. For 40 years I have been traveling. I never stay in one country more than three months. Why? Because I was interested in seeing, and if I stay longer I become blind.
