I use random people in scenes all the time. Sometimes a person is positioned in such a way as to create a scene. Street photography is all about people in scenes. One technique is to create compositions where people are juxtaposed to nearby architecture or structures. A simple example is a person waking past an archway. Looking for a composition is like a game; you feel a sense of accomplishment when you capture one. I haven’t played but maybe it’s a little like Pokémon Go.
I took this at Bayfront Park in Sarasota recently. The park is an island with a trail around it and these swings are spaced every fifty meters. I come here when I want to do a mixture of people and landscape photography; it has plenty of both. As I walked behind this lady I think she knew I was taking pictures because she glanced back. She didn’t seem to mind so I paused to get several more.
I use people in this way all the time. Of course it’s better to be coy about it, if people become aware of what your doing they may change their behavior. Lately I’ve taken to carrying only a small 35mm lens on my camera. That way it doesn’t stand out so much and I can almost pretend I’m a casual shutterbug. In reality I’m on an undercover mission.
One time it backfired on me. I was trying to be nonchalant as I took a picture of a rundown garage in a gritty part of town. The people inside thought I was snooping on them and started yelling at me. It turned out okay but I should have asked first. Most people don’t mind if they know what you’re doing. And if they do mind, well, no biggie, it’s just a game.
