Perhaps it is because of my time spent in Japan, where strangers often approach each other for photographs. Perhaps it is because I have worked as a nurse, where I deal with complete strangers on a rather intimate, albeit professional basis each day. Perhaps my ease comes from a long history of reading people. I don't know why, I just don't seem to have a problem with the approach. Heck, all they can say is no.
In reality, I think that I can simply pick out the willing. They advertise the fact that they want to be seen like a peacock. It's the people who are the most unusual that not only make the most interesting photographs, but also are the most willing to allow an unknown photographer to document their appearance. People like Mr. Fontana, pictured here, are much more difficult to convince.
