The same photograph can be propaganda, journalism, art or any combination of the three, depending on "our beliefs about them", says Errol Morris.
"We see a photograph based on our beliefs – what we believe about the photographer’s intentions, our political beliefs, and the context in which the photograph appears. Think of all the ways the meaning of a photograph can change. The photographer takes a picture; a journalist writes a caption; the picture appears in an article; it is cropped or appears with other images (which skew the meaning); or it appears in a publication with known (or suspected) political sympathies; often photographs that seemingly express a point of view that we don’t like are seen as propaganda. And photographs that seemingly express a point of view that we do like are seen as journalism. People rarely find fault with photographs that accord with their own beliefs."
