How to enfuse bracketed images, skipping the panorama part in the hugin interface. Thank you to Terry Duell and Erik Krause for the help in overcoming the hurdles. (Created November 22 2014)

The second time is a lot faster than the first time through the very explicit instructions here.
Hugin is an Open Source panorama stitcher and graphical user interface (GUI) for Panorama tools. Hugin page at panotools.
Its strength comes from it being a neat wrapper to a bunch of specialized tools from a community of developers. Its weakness is that sometimes certain tools are updated and change their command line structure which breaks the previous downloaded collection.
To avoid confusion, enfuse merges bracketed images; while enblend is a panorama stitcher. If you have handheld and want to do HDR, you will first need to align the images with hugin, but if you are preparing for time lapses, you will be on a tripod so no alignment necessary.
