Besides knowing that pushing your hand into someone’s face without warning is no way to start or have a dialogue..... his ethical responsibility should begin on equal footing to mine (i don't think that is always remembered & respected)...Then we might consider the circumstances that can make the grayer areas relevant. For example, was I invading his privacy as it appears. No. It wasn't at question. So I made assumptions. He decided that photos of the property from the street were not allowed. So he came after me and wanted the camera & film. Up to this point it seemed black & white. He was clearly in the wrong. But there was more to it. As the confrontation unfolded I did find out the reason for his aggression. I believe he was one of the owners of the property & buildings that my camera was focused on. He thought he was protecting the property... setting aside legalities that's gray. He assumed I had nefarious plans for the site. also grayish. I later heard there had been some protesting of the proposed future of the property. more gray in context. It de-escalated only after I considered his story. Then the man said he would call the police and I rested against a car and said 'ok va bene' (all right) My compass for a ethical standard in regards to photography is at it's strongest when it blends empathy & compassion if i can muster it with self interest. A balance of give and take. With photography that very often means considerations beyond the obvious. Look past the black & white and consider with respect the gray areas. I recently asked myself a question of my ethics as photographer. I posted a nude photo in no words. I had to consider the gray area. The photo was of a long ago love. The black & white of it .. 1st it was with consent (the model not the cat). 2nd I know she was very happy with the photo being exhibited while we were together. But then we lost contact many years back. So I had to ask myself a question knowing there could be no definitive answer. Would she be ok with it exhibited now so many years later.? It was not particularly a tough call on this one more like checking in on my ethics.. When there is no definitive answer is when the importance of ethics really thrives. The easy answers hardly need a gauge. The tough ones are the gray ones that counter our own desires/self interests. Inevitably i find the gray ones need to be balanced by give and take. The question of posting the nude went in favor of my wishes. My ethical balance will be maintained by favoring another next time, at least once.
