I've been photographing Toronto's Homeless People for many years.
It started because while downtown here in Toronto on business, I noticed a homeless person sitting at busy main intersection begging for change.
He was essentially surrounded by a crowd of pedestrians waiting to cross, and as I watched it became apparent that they were all deliberately ignoring him. The light changed and they all walked away without one even so much as glancing down at him.
It occurred to me that the homeless were essentially invisible to the rest of us becaue in most cases it was just easier to look away or ignore them, than to perhaps make eye contact and confront an unpleasant situation.
I decided then to start photographing them and perhaps in some small way make them more visible.
The first time I went out, I drove to a street where I knew a number of homeless persons "lived", pulled over, rolled down the window, took a shot with a long lens, and quickly drove away.
I stopped a few blocks away and was overcome with shame at what I had just done. not because I had taken the picture, but because of the manner in which I had taken it.
I realized that to get any meaningful photos I'd have to first get to know the people I was photographing.
So I drove back, parked my car, got out and walked up to the first street person I saw, introduced myself, shook his hand, asked his name and began to talk. We spoke for a long and with his permission I took some pictures. He was kind enough to give me a lot of insight into his life on the street as well as lessons in street ettiquette and even walked back with me to the colony of street people I had first photographed and introduced me to them. For the next couple of years, I spent a great deal of my free time downtown, getting to know many street people and photographing them.
Except in cases where people are sleeping, or perhaps unconscious, I always ask permission, and if it is refused, I don't snipe from long range. And if I'm given permission to take a shot, but asked not to show it publicly, that request is always respected.
And yes, I often do give them some money, but it is never contingent on permission to shoot. I always make that clear. They'll get the dollar or two regardless.
Have my pictures made a difference? For the most part no, but I didn't expect I'd change the world when I started doing this self-assignment anyway. On the few occasions when I've lectured at photo clubs and shown a photo-essay, the comments I've received about my pictures "making those who are invisible, visible" are at least a tiny step, and I suppose if I've heightened even one person's perception about homelessness it's something.
