I usually take candid pictures, usually without asking for permission. Usually I have no problem, but once in a while I encounter a person who vehemently objects, claiming that I am stealing their soul. It happened to me recently in the Caribbean island of Bequia, when an old woman covered her face long before I had any idea of taking her picture, and waved me away. In situations like this I simply pass because I have no interest in taking pictures of people against their will, rather than because I sympathise with their beliefs. In fact, I have no idea what these people are thinking. Can someone explain?
