Gary Knight went to Iraq ahead of the conflict in 2003 to document the brewing war. He kept diaries of the events, which will be published alongside his photographs in an exhibition at the Bronx Documentary Center in New York, starting Thursday, March 14, in conjunction with the 10-year anniversary of the war’s start.

War is fraught with danger, even for journalists and especially for photographers who must get up close to their subjects to frame an image. Fashion is far less perilous, though photographers must also get intimate with their subjects. There are photographers who shoot both: battlefields and runways, guns and glamour.

By the 1850s, newspapers had started sending photographers to document wars. Today, photography has become an expected standard of the media’s coverage of conflict. Portraiture can add a personal, individualized connection between civilians and soldiers.

During his first visit to Libya in 2011, Mads Nissen photographed the people involved in the emerging civil war. Nissen returned to the hotspots of the civil war in 2012 to find demolished, abandoned buildings and homes. The silence, he said, was in ways scarier than the noise of war.

The only warning sound is the roar of a plane flying overhead. Residents of Aleppo, Syria, keep constant watch on the sky, hoping to evade death from an airstrike. Bombs drop daily now, says photojournalist Ricardo Garcia Vilanova. Safety is a matter of chance, and the odds become worse with time.

In a war zone like Syria, photojournalist Seamus Murphy knows that a helicopter hovering over a hospital is a bad sign. The Russian-made MI8 launched two rockets into the building. Working with a fixer in Turkey, Murphy spent three days in Syria last week.

A decade ago, seven of the world’s leading photojournalists banded together to form VII Photo Agency. Their book, “Questions without Answers: The World in Pictures by the Photographers of VII,” will be released by Phaidon on May 1. It is one of eight books to be released by the agency this year.

Photojournalist Tim Hetherington lost his life in Libya last year while covering the country’s civil war. His work from Liberia and Afghanistan, exhibited at the Yossi Milo Gallery in New York, focuses on the individual's perspective of experiencing war. Hetherington's joint-effort film, "Restrepo," was nominated for an Oscar.
