Many of my favorite Winogrand photos involve the subject realizing they are being photographed.

I recently saw a youtube video of an interview with, I think, Winogrand that showed clips of him shooting on the streets of LA. He was doing the dance that Lensworker describes and I remember thinking how most of his subjects seemed a bit disturbed as he approached, because he looked so jangly doing his dance. They seemed even more perturbed immediately after he triggered his shutter, as they weren't 100% sure but thought he had just taken a picture of them. Now this may have been aggravated by the video camera presence for the interview. In any case, I think the slight pre-exposure unsettling may have actually made some of his shots more interesting. Personally, I can't see myself doing it. I'll see if I can post the link later. Best of luck to you.
