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

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

What matters most to me is to take photographs; to continue taking them and not to repeat myself. To go further, to go as far as I can.

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.

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.

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 never stay in one country more than three months. Why? Because I was interested in seeing, and if I stay longer I become blind.
