Photography, like any other art, is a form of communication. The artist is not blowing bubbles for his own gratification, but is speaking a language, is telling somebody something.

If tone is granted to be subjected to control, why not line also, which has equal emotional significance? And if line, why not shapes and forms? And if shapes and forms, why not allow elision or emphasis of detail? And if all these things are allowed, what becomes of the record of actuality ?... Sunk without a trace!

Emotion may be expressed, or the utter lack of it may be expressed, but the only important fact is that of expression.

Nature is an unpleasing, stupid, lumpy, blowsy wench.

Thoughts and emotions cannot be photographed, despite the protestations of some mystically minded portraitists. Physical fact is ultimately the sole pictorial material.
