"You're getting stuff the New York Times never will," Al Rockoff says, pointing to a series of framed images before him. "That's the truth."
The stuff is extraordinary: A single human hand being carried away by stretcher from the scene of a rocket attack.

A line of US Marines bracing against the wind kicked up by helicopter rotors during the American evacuation from Phnom Penh. For almost a decade, beginning as a US Army combat photographer in what he refers to as "the American war" in Vietnam followed by a stint as a freelance photographer from 1973-1975 capturing the brutal insanity of the Cambodian conflict and the eventual triumph of the Khmer Rouge, Rockoff gained a reputation for unforgettably macabre images he sold to Newsweek, AP, UPI, and the New York Times.
It was a brilliant career prematurely aborted by what he describes as a media "blacklist" against the use of his work following Rockoff's evacuation from the compound of Phnom Penh's French Embassy, along with the last remnants of the city's expatriate population, on May 7, 1975.
"I've been stiffed and ostracized," the bearded 52-year-old who was portrayed by the actor John Malkovich in Roland Joffe's film The Killing Fields says bitterly. "It's payback time."
Payback, for Rockoff, is a special exhibition of his work in Phnom Penh to commemorate the 25th anniversary of the fall of the city to the Khmer Rouge on April 17, 1975.
It's an exhibition that Rockoff, out of all the photojournalists who covered the Indochinese conflict, is uniquely qualified to give.
"I shed blood for my art," he says of his passion for combat photography that led him to be wounded nine times and left him with the same unsettling thousand yard stare discernible in many of his subjects.
But it was Rockoff's coverage of the fall of Phnom Penh that was the pinnacle of a career he describes as "creative endeavor with an adrenaline rush."
As the Khmer Rouge entered Phnom Penh on April 17, 1975, beginning the systematic murder of military and government officials of the defeated Lon Nol regime and the evacuation of the general population to the Cambodian countryside, Rockoff roamed the city snapping incomparable photos of a society in its death throes.
"When the Khmer Rouge entered Phnom Penh people lined up along the sides of the street waving, while loudspeakers announced `the war is over , do not resist,'" he recalled.
"People though the worst was over ... little did they know it had just begun."
Rockoff had an eerie first hint of the harsh reality of Cambodia's new order later that afternoon, when along with New York Times correspondent Sidney Schanberg and Cambodian interpreter Dith Pran he was detained by Khmer Rouge troops on the Japanese Bridge in central Phnom Penh.
"A Khmer Rouge soldier opened up Schanberg's travel bag and found his US$10,000 of `emergency money' and some underwear," he explained. "The soldier fanned through all the notes carefully, then took the underwear, leaving the money in the bag for Schan-berg."
The symbolism of the soldier's disdain for money did not escape Rockoff -- in the pure, hard flame of the Khmer Rouge revolution, money was a fetish of the old society that was coming to an end. Rockoff becomes visibly angry at the mention of Schanberg, whom he accuses of deliberately and maliciously sabotaging his career.
