Thanks!! Homeless people in the streets have in their faces an unique feature that only they have. I don't know if you have read ' An Aperture Monograph' by Diane Arbus where she says about her subjects in the street, that they no longer had anything to prove because they had already passed their tests in life. For that reason, in them lies one of the best character examples in a photographic image. If you can do it, don't think twice, you will find a world of possibilities and it will be an emotional journey. JC
