The article discusses the photographer Na Kyung Taek, who secretly captured and shared images of the brutal suppression of the Gwangju Democratization Movement in South Korea in 1980. Despite the risk to his safety, he provided photographs to foreign news media, shedding light on the military atrocities. His images, along with those of another photographer, became crucial evidence of the government's crackdown. Although Na's identity remained hidden for years, he was eventually recognized for his courageous actions and his photographs were included in Unesco's "Memory of the World" program. Na continues to advocate for the truth about the Gwangju uprising, countering disinformation and preserving the historical record through lectures and exhibitions. Despite his regret over not capturing a mass shooting on film, Na's bravery and dedication to documenting the truth have left a lasting impact.
