This Civil War photograph was ...wait, are those porta-potties in the background? And a station wagon? Yes, this photograph is less than a year old, but you can imagine someone cropping it and using it as a Civil War photo sometime in the future. Photographer Richard Barnes shoots Civil War reenactments using techniques authentic to the period, such as wet-plate photography. The picture shown here was taken at the 150th anniversary reenactment of the First Battle of Bull Run. See a gallery of Barnes' reenactment photographs at National Geographic magazine. Link
