Rob, you, even more than I, should know that there’s no way around wasted effort in this racket. I look at my collection of what I think are my best street shots, spread over more than sixty years, and I think of all the thousands of rejects along the way: the shots I blew learning to compose, the shots I’ve missed because I wasn’t quite fast enough with the camera, the shots I’ve missed because I was set for work at a distance and the thing happened close-in. As HCB said: “It’s always luck. You just have to be receptive. That’s all.”
