Photography ethics is a big deal and something I find both challenging and fascinating. How does @stevemccurryofficial get those shots in Muslim countries where people shun away or are even offended by photography? Does he sit down for tea and build relationships? Does he pay? And how does he convince his subjects to carry on as normal without changing their stance or facial expression? I've had a man chase me down the street in Beijing, a local lady shout at me for exploiting the poor in Sri Lanka (even though my subject had happily agreed to the shot), the police force got physical in Moscow. I've never intended to harm anyone and have often been refused magnificent shots after asking, shots which had I not asked, I probably could have got away with. I think there is not one rule for all, you have to sense the situation a little. If in doubt, it's probably best to ask... In the case of this candy floss man, he was walking fast and I was trying to keep up with him. I snapped this just as he turned and clocked eyes on me. It could have gone either way but his body language was relaxed so I took the opportunity to show him his picture, to which he cracked a wide smile. Job done.
