Imagine yourself, camera in hand, walking through a busy metropolis. The sights, the sounds and the smells of a bustling city overwhelm your senses. People all around you are scurrying to and from work. Others are sitting in outdoor cafes enjoying lunch.
As you survey the scene, you spot an elderly man across the street sitting alone in a wheelchair. He holds a small cup out and thoughtfully watches the activity. You’re amazed at how seemingly invisible he is. No one gives him a second glance. In fact people seem to be going out of their way to avoid him.
