street photography | Detroit, MI
Once you get over the fact that people are going to see you taking their photograph, street photography gets 100x easier. You just have to be prepared (and mature enough) to explain yourself if confronted. The fact is, the great majority of folks aren't paying attention, and many who do notice don't care - especially if your camera doesn't intimidate them. Often, those that will confront you have no idea what street photography is, so they automatically assume the photos might be used for something embarrassing, or something they should get paid for.
I do believe that people in public spaces are open game (read: legal) for editorial street photography, but I guess lately I've decided to avoid taking photos of homeless people without some sort of respectful engagement first; they care about what light they are seen in, too. That's an interesting topic to me; some guys do it so well, with utmost regard for the dignity of the subject and with a clear vision for the message that they intend to convey (which is much more than a simplistic "look, I survived the 'hood without getting robbed of my gear! check out this homeless guy!" message). I suppose that's a discussion for another day; I'm sure there are many, many viewpoints on it.
Anyway, this guy, like most that I run into, was glad to have his photo taken. Being so retro GQ, I don't think he would have had it any other way. :)
