Smile...you're on Candid Camera!

I have been practicing photographing people with what I call "belly shots." I hang my camera around my neck, and when I see someone I'd like to capture, I act nonchalant, look the other way, more or less aim, then press the shutter furtively with my thumb, hoping that the angle from my midriff will be a good one. That's what I did with these three ladies, but I think they suspected something. Oh, well. Practice makes perfect.
