There are always two people in every picture: the photographer and the viewer.
Photograph not only what you see but also what you feel.
A good photograph is knowing where to stand.
There are no rules for good photographs, there are only good photographs.
I do not think there is any question of photography being an art form!
I expect to retire to a fine-grained heaven where the temperatures are always consistent, where the images slide before one's eyes in a continual cascade of form and meaning.
