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, a more selective, more acute seeing eye by looking ever more sharply at what is going on in the world.

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.

I agree that all good photographs are documents, but I also know that all documents are certainly not good photographs. Furthermore, a good photographer does not merely document, he probes the subject, he 'uncovers' it.

Photography was the medium preeminently qualified to unite art with science. Photography was born in the years which ushered in the scientific age, an offspring of both science and art.

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

Pictures are wasted unless the motive power which impelled you to action is strong and stirring.

Some people are still unaware that reality contains unparalleled beauties. The fantastic and unexpected, the ever-changing and renewing is nowhere so exemplified as in real life itself.
