Processing photos costs me enormous mental effort because I'm faced with countless possibilities and I'm incapable of choosing just one
I love it, but it's also exhausting.
I download files straight to /tmp (RAM), so when I closed my RT laptop I also lost the download and the sidecar file. When I'm back on that laptop I'll see if it's in the cache; if it is then I can share it with you. The absolutely only parameter difference between the "HDR" and the normal image is that I had to adjust the exposure in one to match the other.
The haze. I used to fight such things, now I just go with the flow. Maybe one could get rid of it in post-proc (Retinex in RawTherapee and luminosity masks in GIMP come to mind), maybe it could be even done to look realistic, but it was there, it gives the photo its look, so embrace it.
...Though now I am tempted to try removing it, just for kicks
Dealing with real high dynamic range scenes is not simple. Endless possibilities. Sometimes curves alone work great, sometimes they're not enough. Sometimes tone-mapping works, sometimes not. Sometimes you have to dodge and burn and use luminosity masks. There is no one-size-fits-all. Maybe with another 30 years of experience I'll be able to offer some advice, but not now.
