I saw John in Tampa, a couple of months ago. He was sitting on the sidewalk with a forlorn look. John had been going through some tough times, and was homeless.

I make it a point to look all subjects in the eye when photographing. Whether the person is homeless or a multimilliuonaire, it's just his/her eyes and mine, making contact. This way, I endeavor to always treat subjects as equals, and (hopefully) never inadvertently create a condescending point of view.
