luminance hdr works again. I wonder what changed?

When you do the final stitching you have to check off what kind of output you want.  By default it will give you a jpg or tiff, but if you look further down the  stitching page you will find "High dynamic range merged stacks".

That being said, I don't think that this is what you think it is.  That will output a HDR file which is an image that contains a lot more light data than can be viewed directly in an image viewer.  They are used heavily in programs like blender or in video games.

What you are looking for is called tone mapping where you compress a broader level of light data into a visible space, which is what LuminanceHDR does.

I would stick with LuminanceHDR and just use it's interface to hugin to align images properly.

doing it the other way around you would still have to load the HDR file that hugin makes into LuminanceHDR so that you could get a visible image out of it.

All that being said, you could select the "Exposure fused stack" option in hugin and get an HDR image, but you have little to no control of how the output will look, so you are better off using LuminanceHDR again.

I just found out you can do HDR with hugin.

How do you do it? I found the instructions but:  
  1. Take bracketed shots of your scene.
    done

  2. Open bracketed images in Hugin. Align - let's say - the middle exposures together and set the stacks in the Images tab.
    1. If your stacks don't align (shot hand-held, sloppy panohead, etc.), set some control points inside stacks and align them too.
      done.... not sure about 'set[ting] the stack in the Images tab'

  3. Stitch the panorama with hugin and 
    done
  4. enblend to HDR file.
    not done. how?

  5. Optionally tonemap the result with qtpfsgui.
