"All quite true, Rob, but you don't send the same negative to a thousand D&P units. You find an experienced printer and work with him until he understands exactly what you're after. HCB's prints, for instance, tend to focus on middle grays, which, in the hands of Voja Mitrovic, were very well done and very consistent. It's interesting to compare HCB's work with Josef Koudelka's. Mitrovic printed for both of them and the emphasis in Koudelka's prints is quite different from the middle gray thing in Cartier-Bresson's."
Ah, 'straight' second-guessing of a higher order, then!
