Hmm. Why shoot JPG? Before you even start HDR processing, you've lost most of the dynamic range. I think that would particularly affect the extremes - such as the sun. I shoot RAW format. On my camera, that's 48-bit color (16 bit per channel). Then I use Rawtherapee to convert to 48-bit TIFF and continue from there. I also use 2 stop differences (base 0EV, +2EV, +4EV, -2, -4). Since your goal is EXR, I think it better to start with an HDR format and keep it that way all the way through. >I wanted to try other settings but now the stitcher fails every time. >I'm >not sure if the same thing happens with TIFF, but I need this to be in >32bit EXR in the end. > >Additionaly - >recently I opened a different topic featuring a panorama of a riverbed >(https://groups.google.com/forum/#!topic/hugin-ptx/aRAfBvEwRdk), and it > >suffers from the same issue.
