Experiments in photoshop

I was given the challege to make this photo from a Civil War Reenactment look like it was taken back then. It gave me something to do today at work, I called it research for future projects and it was a slow day my first assignment isn't until 7pm. It's is amazing what can be done in Photoshop, I am slowly learning.
