We might think that we know the rules of composition and have a sense of esthetics and a background in fine art. Still, this in no way prepares us to automatically distinguish famous photographs from billions of pictures that have been made, unless some feature of style, content and circumstance allows one to deduce the authorship.
The pictures that TOP uses to demonstrate that we all know nothing about pictures, could be missed by a lot of bright and talented photographers and art historians if that artist's work was off his/her radar. It doesn't mean the critique is utterly foolish and naive, as TOP implies, rather that we do not know the body of work of famous photographer's well enough.
Of course, some of the pictures are iconic and it's amusing that silly comments can be made about a war photographer being too close to his subjects. However, it was indeed true as Robert Capa, the founder of Magnum, was killed, just because of that. He got off the truck and headed to the action and was blown up by a mine May 25th 1954 in
"an obscure battlefield in Indochina".
Had he used a telephoto lens, as the silly critique suggests, he might have survived a little longer and his work would be no less dramatic or important. It just happens that he made such impressive war photographs, embedding himself fearlessly in the thick of battle. That's his legacy, to view from the position of the men at risk, not the generals peering through telescopes from a bunker on a hilltop.
Still, there's validity, even, terrible irony in the joking and hilarious criticism.
