Third, when I take street photos, I do not hide or sneak around, although I often find myself in the shadows. I am usually out in the open, I am vulnerable, and perhaps that is part of what I enjoy about it. I'm in a lot more danger than anyone I'm taking a picture of. I've got to remain aware of my surroundings, use my periperal vision, listen to people's voices and their tone of voice, gauge the mood of the crowd. I have to use my own discretion and judgment about what photographs to take, which to pass up. Sometimes I stir some dissonence, sometimes not. I try to adjust my responses and my actions accordingly. As some here have noted, one can maintain a positive and friendly outlook without saying a word. Body language, eye contact (or not), a nod, a wave. Sometimes acting with authority, moving with sureness and purpose, are all that are needed. Other times, acting humble works. I seldom have anything in the way of a confrontation. And I do understand people's fears and concerns.
