I believe that Serendipity is a life skill that can be mastered. As a member of a San Francisco photography club, I joined them one afternoon & evening for an expedition to the Cliff House and nearby environs to photograph the area during the so-called “Magic Hour” and maybe catch a great sunset as well. It turns out that a local club of fire spinners chose that same evening to meet and practice their craft. Photographers love interesting subjects, interesting subjects love photographers, so the leaders of both clubs quickly made a deal; in exchange for becoming their adoring audience, they would become our adored subjects. I have an old Nikon D40 DSLR, and discovered that a very simple setting (2.5 second exposure time) sufficed for my purposes. This photo benefited from a lucky break; a camera flash went off during the 2.5 second exposure (visible camera left).
