a couple of meandering thoughts, in no particular order..
1) There is a homeless daytime drop in shelter right across the street from my house. Seriously - right across the street. Anyhow, when and if they sit on my property, I feel I have the right to take their picture - but seldom do.
2) IN addition to the shelter across the street from my house, theres is also a meth clinic, a second daytime homeless drop in shelter exactly one block due north of my house, a youth jail on the same block I am on, a mens homeless mission (for overnight stays) two blocks west, another two blocks west past that a Salvation Army homeless shelter, the police station is across the street to the east (same block the one homeless shelter is on), - well, you get the point, there's a few other social agencies that have stores and other such places in my immediate vincinity.
My point is - try and take a local picture in my neighborhood and NOT get the homeless in it. Heck, I've even taken family snaps of the kids in the side yard, and inadvertently gotten the homeless in the background, walking down the sidewalk in front of my house.
..and you guys are all debating the ethics of shooting the homeless.. Grrr. if I sound angry - I am. At least you people have the choice to do it or not.
3) as per above, I make a point of NOT shooting the homeless when away from home, or travelling. One exception in the past however. I was shooting in Key West once, and a homeless guy came up to me, and offered to let me shot him for a day, if I bought him a beer. But, if I wanted to shoot him the next day, it cost another beer. The day was hotter then hell, and i kinda liked the guy - being up front and all. So I gave him beer money,a nd had a nice chat with home. A lot of homeless people know the streets very well, and can be an amazing source of information for many different topics.
Well, last point on the soapbox for now.
I guess my point is, maybe you all should be grateful that you have the choice to begin with. Kinda like the debates you see pop up here and on other photo boards and mailing lists about B&W vs colour. I'm colour blind, so I cannot shoot colour anymore than a guy in a wheelchair can do a Stairmaster. Maybe instead of debating ad nauseum which is the right choice, occasionally take a deep breath, step back, and thank whomever you hold responsible that you have the ability to make a choice to begin with. It makes you see the world in a different light when you do that. That kind of outlook on life might even improve your photography a wee bit, regardless of medium.
have a good one everyone
