What is the difference between photojournalism, editorial photography, documentary photography, and telling a “photo story”? Well, I wish I knew. The last one seems to be an attempt to leave the terms behind and go with an obvious meaning which does not need defining. The other three seem to be interchangeable, if not, then quite close to it.
“Photojournalism” is probably the most well know of those terms. We think of news photographers, war photographers, and the like. That one, even if it does have some other definition, already has a practical definition in the minds of common man.
