Steve McCurry's Afghan Girl
A single frame that changed a magazine.
In a refugee camp near Peshawar in December 1984, Steve McCurry noticed a girl at the back of a tent classroom. He asked, quietly, if he might make her portrait. She looked into the lens for a fraction of a second. The Kodachrome frame that resulted became the most recognised photograph in the magazine's history. Her identity was only confirmed in 2002.
Editor's Note
The greatest portraits are almost never posed. They are permitted.
