Quite often photographs gain power from what is omitted from the frame rather than from what is included. - Errol Morris

Correct me if I'm wrong here, but truth is something that arises out of the relationship between language and the world. If I look at a picture alone, it tells me nothing. In the previous incarnation of this lecture, I was going to put a picture of the Titanic and the Lusitania up on the screen. They look very, very similar - four smokestacks. They look almost identical. You look at either picture, true or false? Neither. Put a caption at the bottom of one of them, that changes everything. If you put in the caption, "This is the Lusitania," and the picture is a picture of the Lusitania, then the caption is true. However, the picture itself is neither true nor false. It's just a picture.

Photographs can reveal something to us, and they can also conceal things.

If you want to trick someone with a photograph, there are lots of easy ways to do it. You don’t need Photoshop. You don’t need sophisticated digital photo-manipulation. You don’t need a computer. All you need to do is change the caption.
