At the Met for this wonderful exhibition which explores the role of the camera during the Civil War - a war which left 750,000 people dead. Photography was only twenty years old but more than a thousand artists made hundreds of thousands of photographs during this four year period. Most renowned is Mathew Brady - a former jewelry case maker from Ireland, though he claimed he was from upstate New York. There were many other great photographers at work including another Irishman, Timothy H. O'Sullivan who's image 'Harvest of Death' taken in the afternath of the Battle of Gettysburg is one of the most haunting images from the war. Pictured here is 'Rebel works in front of Atlanta' by George Barnard. He used two negs to make the print: one for the landscape and one for the sky.
