I have been asked so many times: "How do you know when to take a photograph?"
And I remember walking through Paris, and just walking down the street and suddenly smell baking croissants on the air, butter and sugar.
and you oh, and you immediately - you want a corssoiante or a cookie or something right? And then you take two steps and it is gone!
So in the air, on the street was this little zone, for a moment, where the fragance was so rich and compelling...
To me, that is what photography is:
you walk along the street and something happens, and you get it
it is a visual that is as precise as that fragance that is only in the air of the doorway.
