Follow up
I went searching for the street photography thread so I could make my first post in it, only to find that it somehow got deleted. I would have posted this anyway.
I actually received some good advice here from... compuwar, I think (?), who mentioned to make sure to go close to noon. That... almost worked out (had to be later in the afternoon)
Other good advice I received came today when a woman came up to me on the street, pointed out that there were gangs down on one side, and that their most likely concern would be that someone taking pictures with a big camera would be a police officer. That said, I was encouraged to walk down the boulevard.
Four minutes later, a gang of guys on one side of the street starts yelling, not at me, but at the gang on the other side: "YO! HE'S TAKING PICTURES!"
Seriously, my heart almost stopped. The next three minutes proceeded as such.
Me: <waving at the yelling guys, while grabbing my D300 (w/70-200 f/2.8), holding it non-threateningly, and starting to put it away> "Whoa whoa - I don't want any trouble!"
Them: <still yelling to the other guys (total number of people - about 20)> "YO. HE'S GOT A CAMERA. HE'S TAKING PICTURES!"
Me: "Whoa whoa. I don't want any trouble!"
Them: "What are you doing? Why are you taking pictures?"
Me: "I shoot for a magazine. I'm a student over at [university the next neighborhood]. I'm just here taking pictures of the neighborhood."
Them: "Oh. Can I see some ID?"
Me: <pulls out my student ID, which was fortunately close at hand>
At this point, other guys are starting to come over. A brief conference.
"If he was police, would he be wandering in broad daylight taking pictures? He's just a student." "Give him a break."
Them, to me: "You're good. Just keep taking your pictures."
Me: "Seriously, just taking pictures for a magazine. I don't want any problems."
Them: <probably realizing I'm rather disconcerted> "You're good."
The consensus, from some men I passed on the street was, "You're lucky. Normally, they'd kick your ass, take your camera, and send you on your way." [This strikes me as what can go most wrong w/street photography]
So, what I learned:
1. Be able to elaborate what you're doing, and immediately. Have a good reason. You are a photographer - you're not a tourist.
2. If people tell you "No pictures," then put away your camera and say "No problem."
3. Be able to elaborate what you're doing, and immediately. Have a good reason. You're a photographer - you're not a tourist.
4. Most people have some skeletons in their closet. Some people have skeletons bursting out of their closet. Some people might feel like they're being stalked. Other people just want to know what a random person has a big camera pointed at them. Keep this in mind.
5. Be able to elaborate what you're doing, and immediately. Have a good reason. You're a photographer - you're not a tourist.
Seriously, what a day. And by the way - some very good advice earlier in this thread. Whoever said above that dangerous neighborhoods were full of nice people was absolutely correct. Even gangbangers can be nice if you're innocuous and nice too. Just be yourself.
