A little tutorial on our old friend GIMP

Image Editing: Apply Antique Color Tones to a Photograph: "Antique photographs have a certain warmth to them imparted by the development process that can't be replicated by simply dumping the color data from a photograph. At wiikiHow there is a tutorial on using GIMP, a free Photoshop alternative, to take the rich tones from an old photograph and apply them to a brand new photo. The process works with both black and white and sepia toned photographs, and can easily be adapted from the given steps to work with Photoshop too. The above image is a blend of the before and after sample photo from the tutorial. If you don't have any antique photos handy, the tutorial covers where to find public domain images to lift tone samples from. If you're looking to take the opposite route and inject color into a black and white photography check out how to color black and white photos and isolate colors for emphasis."
