I'm pretty far from Trawna, dude. And I photograph in a downtown area that has, to put it diplomatically, seen better days.
The people are tough, quite a lot of them are weird and I don't claim to be able to predict anyone's reaction...you just know how to handle yourself, I guess, and that can't be taught, only gained through experience.
I'm not out to do a freak show, disrespect anyone by crafting an image of them, or torque a point-of-view. I just photograph what's there.
I'm not sure what you consider so airy-fairy about that -- as jnanian says, it's all about respect for others. I happen to think that's important. It's a statement of principles that applies to human beings everywhere.
