A State Street Family Album is an excellent photo essay by Glenn H Austin. To quote from his site:
This photo-essay is about some poor people who live on the street. They are not cardboard cutout poor people; they are real, living, breathing, human beings. They have problems and feelings. State Street in Madison, Wisconsin is a pedestrian mall that runs from the capitol building to the University of Wisconsin campus. It is home to some of Madison's least fortunate. These are the discards of our society: the poor, the veterans, the homeless, the drug addicted, the alcoholic, the runaways, the abused, the unemployable, the people that nobody wants. They deserve something better than the lives they lead now, but these photos are not about how bad their lives are. These pictures are mostly about how good their lives are. Stop and talk to these folks that you have previously been ignoring. You will find out something that you didn't know before. You will discover that they are just people.
Go. Take a look.
