This document discusses documentary photography, including photojournalism that records events for news media, social documentary that focuses on a social group or issue, and war photography that documents conflict. Documentary photography aims to record the truth objectively through images that serve as proof, evidence, and accurate representations of real people and events. The document questions how some photographers, such as James Nachtwey and Don McCullin, have used their work to shine light on important issues and potentially change perspectives according to John Ruskin's view of photography's role. It also provides examples of photographers like Sebastião Salgado, Dorothea Lange, and Lee Miller who have contributed to documentary photography.
