War and photography now seem inseparable, and plane crashes and other horrific accidents always attract people with cameras. A society which makes it normative to aspire never to experience privation, failure, misery, pain, dread disease, and in which death itself is regarded not as natural and inevitable but as a cruel, unmerited disaster, creates a tremendous curiosity about these events—a curiosity that is partly satisfied through picture-taking. The feeling of being exempt from calamity stimulates interest in looking at painful pictures, and looking at them suggests and strengthens the feeling that one is exempt. Partly it is because one is “here,” not “there,” and partly it is the character of inevitability that all events acquire when they are transmuted into images. In the real world, something is happening and no one knows what is going to happen. In the image-world, it has happened, and it will forever happen in that way.

— Susan Sontag, On Photography, 1977
