Yann Arthus-Bertrand, famous for 'The Earth From Above', an aerial portrait of our planet, in an interview on televison:
A good photographer is one who has ideas.
I photographed the farmer together with the cow because I wanted him to feel at ease. And to be together with the cow made him indeed feel at ease - because he is proud of her.
First I take a photograph for myself, then one for the portrayed.
