"On Photography" is a collection of essays by Susan Sontag that explores the impact of photography on society and individual perception. Sontag examines how photographs shape our understanding of reality, often blurring the lines between truth and representation. She argues that photography can both document and distort experiences, influencing how we remember and interpret events. In her essays, Sontag discusses the ethical implications of taking photographs, particularly in contexts of suffering and conflict. She raises questions about the role of the viewer and the responsibilities of the photographer, emphasizing that images can evoke empathy but also desensitize audiences to the realities they depict.
