Dutch photographer Ed van der Elsken said: "That's the whole point about photography: you have just to do it, that's the key, a photographer has to take pictures. After that you can bullshit about it any way you want, philosophize about it, harbour all kinds of of droll or splendid ideas and aesthetic principles about it [...]. You have to just make your hours out on the street, among the people. Observing people... For hours and hours and hours, being out there. Making full days."
