A technically perfect photograph can be the world's most boring picture.

The difference in 'seeing' between the eye and the lens should make it obvious that a photographer who merely points his camera at an appealing subject and expects to get an appealing picture in return, may be headed for a disappointment.

With a short lens I can reveal the hidden things near at hand, with a long lens the hidden things far away. The telephoto lens provides a new visual sensation for people: it widens their horizons. And, conversely, the things under our nose invariably look good when blown up really big.

The first impression of a new subject is not necessary the best. Seen from a different angle or under different condition it might look even better. Always study a three - dimensional subject with one eye closed.

A photographer who does not know how to translate his feelings and ideas into a graphically satisfactory form is bound to produce ineffective photographs, no matter how idealistic, compassionate, sensitive or imaginative he may be. For in order to be considered good, a photograph must not only say something worthwhile, it must say it well.

Realism and superrealism are what I'm after. This world is full of things the eye doesn't see. The camera can see more, and often 10 times better.

The camera can push the new medium to its limits - and beyond. It is there - in the "beyond" - that the imaginative photographer will compete with the imaginative painter. Painting must return to the natural world from time to time for renewal of the artistic vision. The key sector of renewal of vision today is the new vistas revealed by science. Here photography, which is not only art but science also, stands on the firmest ground.
