I am a novice in street photography. Today, while I was walking downtown with my camera I stopped on the sidewalk and photographed a middle-aged female jogger as she was passing by in the opposite direction. She came to a stop a few feet after passing me and said I had no right to take photos of her. I replied that I did have the right to take photos of her as she was in a public place and explained that what I was doing was perfectly legal. She asked me what the photos were for. I told her, “nothing--it's just documentary photography.” She continued on to say that her husband was a “cop” (her wording), insinuating a threat, I assume. She asked for my name. I told her my first name and suggested that she should tell her husband and have him look into the legality of my photographing her. She did not respond to this. I added that if she did not like my photographing her I would not take any further photos. She then asked for my last name. I told her my last name and spelled it out to her. She continued with an ultimatum in a nervous, shaken voice, “don’t take pictures of me!” repeated it once or twice more, turned around, and continued on her jog. I did not take any more photos of her and continued on my way in the opposite direction, feeling a bit disheartened by the experience. <br><br> I know I was not legally obligated to tell her what the photos were for or what my name was, but I was trying to make it apparent that I had no ill intentions. Where did I go wrong and how might situations like this be avoided while taking candid photos in public places? Should I set my 50mm aside and purchase a big telephoto lens or should I just work on my approach? <br><br> Notes: I was using a Nikon D50 with a neck strap and a 50mm lens attached. It was about 9AM, Sunday.
