Recomposit is a digital matting and composition tool, that enables you to replace backgrounds in photos. It can work in chroma key mode (Bluescreen) or based on a manual inside/outside edge selection by the user that separates the subject from the background. The software works well, especially with chroma key backgrounds, but requires a lot of patience since interface is slow and not very intuitive.
