So then, for an image to work you pick two of the three: sharpness, blurriness, strong concept.
Wait...didn't HCB state that sharpness is a bourgeois concept?
How do we factor this into the equation?
First, we have to accept that your set of parameters doesn't apply.
Then, thinking about HC-B, we also have to realise that because he was an excellent snapper with a drawing/painting background, it didn't bestow upon him any superhuman qualities that made his every utterance worth recording or swallowing without the minimum recommended dose of sodium chloride, sea or otherwise. Also, we must consider whether his affluent background was bourgeoise or über bourgeoise - I think it tended to the latter - in which case you have to factor in his very own interpretation or concept of what that delightful state actually represented at the time. I suspect he wasn't very crisp in his evaluation, assuming he ever made such an evaluation. which I can't, of course, guarantee, neither one way nor the other.
