John Rudy, adjunct instructor of Civil War Era Studies, was quoted in a June 30 Associated Press story about images from Gettysburg during the Civil War and today.
From the AP:
So in Civil War, photographers sensed opportunity, according to John Rudy, an instructor of Civil War-era studies at Gettysburg College.
Very rarely were scenes of war taken, Rudy said, simply because the exposure time of three to five seconds was too long to capture moving action.
"These men were working for pay. They're part-artist, part-chroniclers, but also keenly aware that their image has to sell," Rudy says.
