Arnold Newman amongst others...

After being told by a hairdresser the pointlessness of the photographer as a
concept...

Those who call themselves art photographers are pompous, arrogant egoists.
- Arnold Newman

It takes a lot of imagination to be a good photographer. You need less
imagination to be a painter, because you can invent things. But in
photography everything is so ordinary; it takes a lot of looking before you
learn to see the ordinary.
- David Bailey

A photograph is neither taken nor seized by force. It offers itself up. It
is the photo that takes you. One must not take photos.
- Henri Cartier-Bresson

Many pictures turn out to be limp translations of the known world instead of
vital objects which create an intrinsic world of their own. There is a vast
difference between taking a picture and making a photograph.
- Robert Heinecken
