Hairdressers in the sun, 1966 by Robert Doisneau 
"Yes, the expectation of a miracle. It’s very 
childish, but at the same time it’s almost like an act of faith. We find
 a backdrop and wait for the miracle. I remember a backdrop that never 
worked for me, possibly because I didn’t wait long enough, or didn’t 
return to it often enough. In the foreground you can see the steps of 
Saint Paul’s church, the background is a perfect faubourg, as you 
imagine them from literature or movies. I frame it in my viewfinder, 
from rue de Turenne to a shop called Le Gant d’Or, and wait there for an
 hour, sometimes two, thinking, “my God, something is bound to happen”. I
 imagine events I would like to photograph, one wilder than the other. 
But nothing happens, nothing. Or if it does – bang – it’s so different 
from what I expected that I miss it. The miracle did take place, but I 
wasted it, because I didn’t pay the right kind of attention. When you 
are tired, you become unable to react, your emotion is no longer 
available."
