Expanding on and engaging with the subject matter of her 1977 classic On Photography Sontag explores what meaning there is to be found in photos of war and atrocities. With characteristically incisive questions and insightful arguments she prompts us to challenge our own assumptions that these photos represent objective truths, and to critically assess how these images affect us. Published in 2003, Sontag brings in newer examples from the war in the former Yugoslavia to the 9/11 attacks. Although still photography is her primary subject, she does discuss TV and many of the questions she raises are still relevant in our current social media context. Sontag's work is always mind-expanding but I wished this work was longer and that she had gone deeper on audience impacts.
