The document discusses John Tagg's argument that photographs are not neutral representations of truth or reality, but are highly coded and manipulated representations of power. Tagg asserts that the camera wields the power of the institutions and agents that deploy it, not power of its own, and that the photographs it produces stand as authoritative evidence or truth only to the extent guaranteed by those institutions. The document provides examples of photographs like "Migrant Mother" and "Flag Raising on Iwo Jima" to illustrate how photographs can be used to construct and naturalize particular political and social orders rather than objectively documenting history.
