If you’re not following what documentarian Errol Morris has been writing on the nytimes blog “Opinionator“, you’re missing some of the most intriguing, controversial, exploratory contemporary writing about photography.

His latest posts, about a photograph of a Mickey Mouse doll on a war-torn street in Lebanon, including an at-length interview with the photographer Ben Curtis, have been particularly revealing. Have a look!

I invite the Times readership to respond. Is it photojournalism, propaganda or art, and why? My own answer is below.

Answer: There is no difference. The photographs are the same. (Although the three captions are different.)
