From PDN:
Leroy was part of a generation of photojournalists who made their names in Vietnam – some others include David Burnett, Don McCullin, Gilles Caron, Larry Burrows, Tim Page and Dirck Halstead – by taking advantage of the access afforded to journalists there.
“We rode in military planes, did helicopter assaults during operations, walked with units, everywhere, anytime,” Leroy recalled in a 2002 interview with PDN. “We were not subjected to censorship. It was unprecedented, and it will never be repeated again. We have now entered ‘the brave new world’ where disinformation and censorship are being implemented and access reduced to photo opportunities.”
In the same interview, Leroy described her how she traveled to Saigon at age 21, with a Leica and $150 and no combat experience. “I had never heard a gun fired in anger before, and I spoke three words of English,” she said.
