Great shot. Where you shooting through a window? There is some sort of reflection or something in the lower third of the image under the back seat doors of the taxi. Otherwise, I love it.
Nope, I was on foot, nothing in between me and the subject. I do see what you're talking about. I think it's actually the light reflecting off the taxi's windows onto the street. I shot this at f/16 and 1/20 sec, handheld. After many failed attempts.
