War photography: From first shot to homecomings

Can photographs bring the full reality of war to those who have never been in battle?

An exhibition at the Corcoran Gallery of Art in Washington DC shows a range of photos - iconic and unknown, profound and not - all about war and its aftermath.

One photographer included in the exhibit, Louie Palu, believes photographs can be a safe way for people to reflect on war without becoming shocked or overwhelmed.

The BBC's Jane O'Brien talks to curators and photographers about what these photographs tell us about the realities of war and the people who fight in them.
