You can change people's minds using words or photos. Since the advent of the camera, there have been a handful of photo journalists who have changed what people think about events, wars, cultures, and places. For instance, Eddie Adams took one of the most iconic images in history. "The Saigon Execution" is a photo of General Nguyen Ngoc Loan executing a Vietcong prisoner on the street during the Tet Offensive. This photo not only won Adams the 1969 Pulitzer Prize for Spot News Reporting, but this image will always be associated with the Vietnam War.
Adams' photos transformed the American view of the Vietnam War. It shed light on the atrocities committed on both sides. His photos were even able to help persuade Jimmy Carter to grant asylum to 200,000 refuges. The glory that you can receive as a journalist is hard to compare in other lines of work. You can literally change the course of history. Pretty glorious.
