I've been pondering this for a while. What's the proper way to photograph strangers on the street candidly? I live in a college town and there's always interesting people to take pictures of, but I'm not the type of guy to walk up to some stranger and say "May I take your picture? Act normal." Is the normal consensus that quick shots done stealthily are the best way to take full advantage of some of the things I see around here? Or am I SOL? Thanks.
