For the most part, this is a wonderful series. IMO all are fair game for street photography. That said, I typically do not photograph homeless people unless I am trying to make a statement to support them. I like "Curiosity" showing a poor homeless person and many well off people staring at him as though he was a freak. He is not a freak, he is a person! A person who may be an addict or just not had the fortunate life that many of us have.
"Dignity" I defiantly would have taken the photograph. I would struggle deciding if I'd post it. I would really want to post, but I probably would not.
I absolutely love the first shot. The snow, the deadpan looks, the White/Black writing. It is a photograph I wish I'd have taken...
I try very hard not to embarrass the people I photograph. They are people and deserve our respect.
