One of the most intense portraits I have ever seen is the portrait of the Afghan girl, taken by photographer Steve McCurry, in December 1984. The photograph is also known as the Afghan Mona Lisa.
The young girl was Sharbat Gula, aged 12.
When her village was attacked by Soviet helicopter gunships, her parents were killed, and she made her way with other family, to the Nasir Bagh refugee camp in Pakistan.
The photograph made the cover of National Geographic in June of the following year.
Sharbat Gula returned to Afghanistan in 1992.
For gear-heads: Nikon FM2, 105mm f/2.5 lens, and Kodachrome film.
