I just got back from cambodia, and i did take alot of pictures. The most interesting things to me were people, just doing stuff and going about their everyday life. Most of the time, just smile real big and they don't mind. if your photo-taking is obstructing them from doing something, like make a sale, then maybe thats wrong, but most of the time they get a real kick out of seeing their own picture after you have taken it. but then most people in cambodia are really nice and don't mind the tourists. as a very cambodian-looking tourist i get my fair share of stares, and trust me if they had cameras they'd be taking my picture too... i don't mind. its just a way of recording the things i've seen and the things that have some poignant meaning to me. I'm not going to make money off this. if i could i'd develop pictures on the spot to give to the subjects. but thats impossible for a place with barely any postal service.

just my 2 cents worth on this...
