Testament, published by Powerhouse Books, is a collection of his powerful photographs and writing, spanning more than a decade of coverage from some of the world's major conflict zones, including Liberia, Lebanon, Afghanistan, Iraq, Haiti and Libya. Proceeds from sales of the book go to the Chris Hondros Fund, which supports the work of conflict photographers and aims to increase awareness of issues that arise from reporting in war zones.

In this gallery, we present a retrospective of Hondros' work.
