      Just try it with a set taken this morning, the sun was very bright and my camera was pointing directly to it so without enfuse, one side would be undexposed and the other is super overexposed.
      http://picasaweb.google.com/sillyxone/Panorama/photo#5184409804177189922

      At first, I converted the RAW into a 16-bit TIFF, then fed it to Autopanog and Hugin, no problem at all, but I don't know how to extract different exposures out of the final TIFF file to feed to Enfuse, so it's just sitting there. Beside, I heard that RAW file store in linear mode while TIFF applies the gamma so there are some clipping in the highlight and shadow. I don't think I will follow this direction.

      So, I converted three 8-bit TIFF from RAW for each shot, put those with the same exposure in same directory as an exposure set. Using the same .PTO file for all three exposures, Hugin had no problem creating three identical panoramas at 3 exposures. Enfuse obviously had no problem blending the panoramas together.

      So far so good, I'm happy with the result. Probably I will write a small shell script to speed up the process to make the experiment process easier.

      thanks for the guide,

      Yes you can create 16bit images from your RAW data, stitch them with
      hugin/enblend to 16bit output, and then run this tool that merges
      faked brackets with enfuse.

      Though I don't think you will get the results you are expecting, do
      make sure that your 16bit input images are not clipped and that they
      have a gamma of 2.2.
