What is the subject matter of this apparently very personal world? It has been suggested that these shapes and images are underworld characters, the inhabitants of the vast common realm of memories that have gone down below the level of conscious control. It may be they are. The degree of emotional involvement and the amount of free association with the material being photographed would point in that direction.

However, I must stress that my own interest is immediate and in the picture. What I am conscious of and what I feel is the picture I am making, the relation of that picture to others I have made and, more generally, its relation to others I have experienced.

I may be wrong, but the essential illustrative nature of most documentary photography, and the worship of the object per se, in our best nature photography, is not enough to satisfy the man of today, compounded as he is of Christ, Freud, and Marx.

As the language or vocabulary of photography has been extended, the emphasis of meaning has shifted, shifted from what the world looks like to what we feel about the world and what we want the world to mean.

Producing a photographic document involves preparation in excess. There is first the examination of the idea of the project. Then the visits to the scene, the casual conversations, and more formal interviews - talking, and listening, and looking, looking. ... And finally, the pictures themselves, each one planned, talked, taken and examined in terms of the whole.

For some reason or other there was in me the desire to see the world clean and fresh and alive, as primitive things are clean and fresh and alive. The so-called documentary picture left me wanting something.

The business of making a photograph may be said in simple terms to consist of three elements: the objective world (whose permanent condition is change and disorder), the sheet of paper on which the picture will be realized, and the experience which brings them together.
