During the American Civil War, photographers like Matthew Brady and Alexander Gardner brought the visceral, grizzly reality of the battlefield to the doorsteps of civilians. For the first time, the "glory" of war was challenged by images of bloated corpses and scarred landscapes. This marked the beginning of a long history where the camera served as a sobering check on military romanticism, forcing the public to confront the true cost of political decisions.Beyond the battlefield, photography became an essential instrument for social justice and legislative reform. In the late 19th and early 20th centuries, reformers like Jacob Riis used flash photography to illuminate the dark, cramped interiors of New York City’s tenements.
