TIME highlights the photographs that have had the biggest influence on our times.
TIME announced on Thursday the 100 most influential images of all time, from some of the first photographs ever taken of U.S. national parks, to iconic images of presidents and rock stars, to one of the first photos posted on Instagram from North Korea.
“In the process of putting this list together, we noticed that one aspect of influence has largely remained constant throughout photography’s nearly two centuries,” TIME's editors write. “The photographer has to be there. The best photography is a form of bearing witness, a way of bringing a single vision to the larger world.”
Take a look at some of the most influential photographs in history, and see more at TIME 100 Most Influential Photos.
The photo book is available to buy at the TIME Shop.
