...but not always the truth. Or perhaps, when meaning isn't clear it's easy for people to read things into a picture that aren't there, or bend the meaning to their own ends.
This story on Slate.com is a prime example. In the foreground are five people sitting and talking, while in the background a huge bloom of dust and smoke rises where the World Trade Center towers were. The date is September 11th 2001.
Five years later the photographer then put a slant on the picture which is basically a fabrication, inferring that he knew the nature of their discussion and how they were reacting. Two of the subjects decide to hit back with the truth.
It's a worthwhile reminder that you can't believe everything you see and read.
