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.
What matters is not what you photograph, but why and how you photograph it. Even the most controversial subject, if depicted by a sensitive photographer with honesty, sympathy, and understanding, can be transformed into an emotionally rewarding experience.
It's nothing but a matter of seeing, thinking, and interest. That's what makes a good photograph. And then rejecting anything that would be bad for the picture. The wrong light, the wrong background, time and so on. Just don't do it, not matter how beautiful the subject is.
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.
Every successful photograph, except for lucky shots, begins with an idea and a plan. The more precisely a photographer knows what it is he wishes to do, the better the chances are that he will do it.
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.
Photographers - idiots, of which there are so many - say, "Oh, if only I had a Nikon or a Leica, I could make great photographs." That's the dumbest thing I ever heard in my life. It's nothing but a matter of seeing, and thinking, and interest.
