Street is not easy, at least not for me. I keep thinking (fearing

) I'm gonna get yelled at, or worse, in a fistfight, and fear of people's reaction is death to street. Sometimes I feel sneaky and scurrilous. The only way I'll ever get better is to force myself to keep doing it.
I hear the best way is to grab and go ... Be a lightning bug. You're gone before they realize what happened. Compose and get what you can and toss out the turkeys with no regrets. I do a little of that. Really I traipse around and try to look for something expressive and grab it. If I get it, I get it. Sometimes I'll camp out in a place for 20 mins or so and snipe. I wear darker clothing so as to blend in. I carry one lens usually a 50 mm.
What I struggle with, is that images that seem great to me are only that way because I knew the context at the time. How people were shouting at the homeless man a moment before, and he stoically goes on. But the picture doesn't show that. Just an expressionless bearded man. My street pictures many times aren't strong because the PICTURE doesn't tell the story that I remember and have an emotional attachment to. The pictures wind up only having meaning for myself.
