An interesting piece appeared in The Guardian by Jonathan Jones. In his article The meaning of 9/11's most controversial photo Jonathan discusses what has come to be an iconic and defining image from the day in question noting motivations, projections and attitudes. It's a riveting read and comes highly recommended for those in the Historical Perspectives of Photography course.
9/11 as a subject is one that a number of artists have tackled. Perhaps one of the more intriguing works is by Hans- Peter Feldman. His work 9/12 reproduces 100 front page covers of newspapers from around the world providing a point of reflection.
