Here’s one of my favorite street portraits from Vietnam. When I think of Asia, especially Southeast Asia, which I have been visiting regularly since 1988, I think of how often one is greeted with an infectious smile here. The street life, with its pungent smells, the deafening cacophony of relentless traffic and the dense population, keep me coming back for more. But it’s also all the smiling people I meet and greet on the streets of Bangkok, Singapore, Saigon and Luang Prabang.
