Award-winning photojournalist Steve McCurry, known for images such as 'Afghan Girl', talks about his work.

He launched his career when, disguised in local attire, he crossed the Pakistan border into Afghanistan 30 years ago.

His remarkable coverage won him the Robert Capa Gold Medal, which is awarded to photographers who exhibit exceptional courage and enterprise.

A recipient of an unprecedented four World Press Photo first prizes in a single year, many of McCurry's images have since become modern icons - from 'Afghan Girl' to his images of the everyday lives of normal people around the world.

The acts of praying, sleeping, laughing, fishing, cleaning and sheltering - all the vagaries of human life - are elevated in poignantly beautiful stills.

In this illustrated lecture, based on his new book, Untold: The Stories Behind the Photographs, he provides a unique insight into his photojournalism.
