Photography can never grow up if it imitates some other medium. It has to walk alone; it has to be itself.

To chart a course, one must have a direction. In reality, the eye is no better than the philosophy behind it. The photographer creates, evolves a better, more selective, more acute eye by looking ever more sharply at what is going on in the world. Like every other means of expression, photography, if it is to be utterly honest and direct, should be related to the life of the times-the pulse of today. The photograph may be presented as finely and artistically as you will, but to merit serious consideration, must be directly connected with the world we live in.

Let us first say what photography is not. A photograph is not a painting, a poem, a symphony, a dance. It is not just a pretty picture, not an exercise in contortionist techniques and sheer print quality. It is or should be a significant document, a penetrating statement, which can be described in a very simple term-selectivity.

Like every other means of expression, photography, if it is to be utterly honest and direct, should be related to the life of the times - the pulse of today.

The art is in selecting what is worthwhile to take the trouble about.

Today we are confronted with reality on the vastest scale mankind has known and this puts a greater responsibility on the photographer.

I wanted to combine science and photography in a sensible, unemotional way. Some people’s ideas of scientific photography is just arty design, something pretty. That was not the idea. The idea was to interpret science sensibly, with good proportion, good balance and good lighting, so we could understand it.
