Steve McCurry, Magnum and National Geographic photographer wrote what attracts him to snap a portrait. " In portraits I look for the unguarded moment, the essential soul peering out, experience etched on a person's face…. When I find the right person or subject, I may come back once or twice, or a half dozen times, always waiting for the right moment. Unlike the writer, once I pack my bags, there is no chance for another draft - either I have the shot or I don't. This is what drives and haunts the professional photographer, the gnawing sense that 'this is it.'

[My portraits] speak for the human connection; a desire so strong that people who know they will never see me again open themselves up to the camera, all in the hope that at the other end someone will be watching - someone will laugh and suffer with them.

From an outpouring of pictures over 20 years, these are the faces I cannot forget. Some stare out of places I don't want to remember. All of them represent chance connections in a world of resilience."
