Lead: During the Civil War the images of Matthew Brady and his associates lent vivid reality to the horror of conflict.

 Intro.: A Moment in Time with Dan Roberts.

Content: Having made his reputation photographing notable figures in the prewar generation, when conflict broke out in 1861, Matthew Brady went to war. Determined to make a complete record of the war, he hired more than a dozen photographers and sent them out as field operatives to mark the passage of the fighting. They used the collodion "wet-plate" process which fixed the image on a thick glass negative. This method required the subject to pose for only a brief period, but still could not capture action or physical movement.
