Yes, and there has been some semantic arguments about that.
I can't argue with the wiki, I'd simply suggest trying the 'HDR' option  
in hugin to see if the result suits.




I've been relying on my memory for this discussion, and thought it best I  
check if I have been getting my story correct.

Unfortunately my memory has been a bit deficient.
Hugin provides choices for outputs, which include;
Exposure fused from stacks, which uses enfuse, and,
High dynamic range, which uses enblend.
Sorry for any confusion.

Go to the Stitcher tab of Hugin and select 'High Dynamic Range", Enblend

Correction, I think it is actually Enfuse that is used to create HDR from  
a set of input images with varying exposure.

Enfuse is part of the Enblend package.

I can't find any option to make enblend write HDR files. How can that be done?

And Hugin is using align_image_stack, which is available as a  
commandline tool as well ;)



...and has Enblend, which will do exposure blending and create HDR, in

I'd try jcelaya's hdrmerge.
It produces DNG (so still raw)
And unlike Luminance HDR, it seems to actually work.

if darktable fails with the HDR as proposed by Robert: try the Software
hugin, a Panoramas and HDR specialist.

If you shot these on a tripod, you can select them both in the light 
table view and click the HDR button.  If it's handheld, I don't think 
Darktable can really do that level of compositing. You'll need to 
manually align them in Gimp or something similar and mask the sky 
appropriately
