Has anyone noticed this seems a little more difficult in 2005? Are people on the street more suspicious of a camera than they were in decades past? I'm naturally a bit shy anyway, and it seems even more of an affront to aim a camera at people in the era of color-coded alerts. But I see good street photography and I think, "Holy bananas, I want to try that!" What techniques have any of you developed for photographing people on the street? I'm not exactly fond of the idea of snapping away without knowledge/consent, although I'll admit that people are more interesting when they don't know they're being observed. So it's a two-part question: the ethics of street photography, and the methods of making yourself part of the scene. Thoughts/comments/caveats?
