Popular Photography magazine have interviewed 8 street photographers and published their insights and advice on their website. Fascinating stuff.

“PPI: Do you try to be “invisible” when you shoot, or do you approach people and ask to take their pictures? Either way, how do you handle approaching people and taking their pictures?
I never try to be invisible. And I almost never ask. I just stand around with a camera and photograph. If I make eye contact, I smile. That’s about it. When you are starting out, you tend to worry about this kind of thing but the truth is most people simply accept your presence if you look as if you know what you’re doing.”
