Enblend is a tool for compositing images using a Burt & Adelson multiresolution spline. Enblend does not align images for you. Use a tool like Hugin or PanoTools to do this.

Enfuse is a tool for automatic exposure and contrast blending. It can be used to fuse an exposure bracketed step automatically into a nicely looking image.
