Enfuse

Enblend-Enfuse are open source console application created by Andrew Mihal and mostly maintained by Hugin developers. It consists of Enblend, an image blending tool useful for creating panoramas, and Enfuse, an exposure fusion (HDR merging) and focus stacking tool that combines the depth of field and dynamic range from multiple images of the same scene (bracketing). Enblend-enfuse accepts images already aligned by other methods.
