I feel lucky. People here are mostly photo friendly. When I am wandering around the neighborhood taking pics, the usual reactions are to ask:
1. What kind of camera is that?
2. Do you use digital?
3. Are you a professional?
4. Do you need me to move or stand somewhere?
I stopped to shoot a dog peering into the cheese shop last weekend and he moved before I got the camera up. The owner asked me about the camera, chatted a while, and asked where I wanted him and the dog so I could get the shot I missed. The dog was not quite as cooperative. With one exception, mentioned earlier, people have been very friendly. But then we also have a local gallery and an artists coop, not to mention the occasional wandering clown.
