People take pictures of people. Saying “Cheese” or “Sex” immediately puts an artificial smile on the other person’s face. Taking photos of people from the front is so 19-th Century. You gotta be a professional photographer to make a realistic portrait.
Last summer, while walking to my workplace in Manhattan, I started to pay attention to the backs of people’s moving in the same direction. Most of the backs were boring, but sometimes, I saw a back that made me wonder what’s the face of this person looked like? Typically, the face was less interesting to watch than the back. So I decided taking pictures of selected backs without even bothering looking at their faces.
Check them out slowly. Don’t critique the quality of the photos – I’ve been using iPhone while walking. Just try to imagine how the front-ends of these people look like.
