Photo Altering

I was reading through the Yahoo news section today and came across this [I think] interesting article on pre-digital photo manipulation. The olden days of photo manipulation must have been a painstaking process...stitching multiple pictures together or working with negatives and darkroom processes seem prehistoric to me now in a world where just one click or movement of the mouse can drastically change a photo with the correct software.

Photo 1. A photo of President Lincoln's head was placed on the image of Southern politician John Calhoun to create the portrait on the left.

Photo 2. Adolf Hitler had Joseph Goebbels (second from the right) removed from the original photograph after a falling out.

Photo 3. The photograph of Ulysses S. Grant on the left is actually a composite of these three different photographs pieced together.

Photo 4. General Francis P. Blair (on the far right end) was added to this Matthew Brady photograph at a later date.
