On the frontlines of photography Many photojournalists have lost their lives or limbs on the battle lines, because the only way to document the violence of war is up close. "Sunday Morning" Special Contributor Ted Koppel looks at the legacy of two noted war photographers, Tim Hetherington and Chris Hondros, who were killed in pursuit of the truth amid the chaos of battle. Koppel also talks with documentary filmmaker Greg Campbell and journalist Sebastian Junger about the dangers faced by journalists in conflict zones; and with former New York Times photographer Mike Kamber, who helped found the Bronx Documentary Center, where youth people are taught about photojournalism.
