I found a fun quiz on Parade.com (via facebook). Can You guess which image is from the civil war and which was taken more recently? Give it a try here.
"Photographer Robert Szabo uses a 19th Century method — the wet plate collodion process — to shoot reenactment scenes. Can you tell which photos are his, and which are real Civil War images shot by renowned photographer Mathew Brady?
Browse these 20 sets of images and see if you can spot the real from the replica."
