One of my all-time favorite photos (depending on the day it's my #1 fav):
I come late to this thread, for historical reasons.
The Klein shot is not a good example of 'honest' street: he shows contact sheets with that shot followed by the kids grinning their butts off.
His story is that he asked them to mug for the camera, and as a very accomplished snapper, he got exactly
what he desired to get.
He goes on to explain that, for him, it is a sort of double self-portrait, for he is both the 'aggressive' kid as well as the 'angelic' one, together repesenting both sides of his own identity and spiritual make-up.
(I've just heard an ad telling me that one can get Viagra pills for under four bucks a pop. That's over KLEB-AM in Louisiana. I had no idea they cost so much! On a regular basis, they make boats seem affordable.)
I should have mentioned that I didn't even notice the difference in focus of the b/ground vis-à-vis the two ladies in the 'kiss' shot. It simply didn't occur to me to look: it was bleedin' obvious where the interest lies. That's the essence of any shot that works.
