The vital elements are often momentary, change-sent things ... a gleam of light on water, a trail of smoke from a passing train, a cat crossing the threshold. Sometimes they are a matter of luck, sometimes of patience, waiting for an effect to be repeated that you have seen. It is usually some incidental detail that heightens the effect of a picture, stressing a pattern, deepening the sense of atmosphere.

Photography is not a sport. It has no rules. Everything must be dared and tried!

When I began to photograph nudes, I let myself be guided by this camera, and instead of photographing what I saw, I photographed what the camera was seeing. I interfered very little, and the lens produced anatomical images and shapes which my eyes had never observed.

By temperament I am not unduly excitable and certainly not trigger-happy. I think twice before I shoot and very often do not shoot at all. By professional standards I do not waste a lot of film; but by the standards of many of my colleagues I probably miss quite a few of my opportunities. Still, the things I am after are not in a hurry as a rule.

A photographer must be prepared to catch and hold on to those elements which give distinction to the subject or lend it atmosphere.

It is part of the photographer's job to see more intensely than most people do. He must have and keep in him something of the receptiveness of a child who looks at the world for the first time or of the traveler who enters a strange country We are most of us too busy, too worried, too intent on proving ourselves right, too obsessed with ideas to stand and stare Very rarely are we able to free our minds of thoughts and emotions and just see for the simple pleasure of seeing. And so long as we fail to do this, so long will the essence of things be hidden from us.

In my portraits I try to avoid the fleeting expression and vivacity of a snapshot.
