Both are fair questions, Oscar.
To #1 I’d have to answer: “Maybe, but not very powerful exponents.” The really great exponents of street are poems that strike your heart with life’s experiences. You can’t just go out for an afternoon and come back with a camera full of good street. As I said in “On Street Photography,” “. . .even when you get good at street photography, you’ll shoot bags and bags of bloopers, a smaller number of not too bad shots, and the rare picture you should be willing to show. Beyond that, there’s the kind of picture upon which you’d be willing to hang your reputation. If you can average one of those a year you’re getting pretty good.”
To #2 I’d say: “Depends on the photographer.” There’s the guy who bangs away, hoping to find something in there he can isolate in Photoshop and pretend was a well-grabbed shot. I see plenty of pictures – even on LuLa -- that clearly express the confusion of the photographer.
