A tone mapping exercise with pfstools. I have extensively used Mantiuk06 contrast equalization in +Luminance HDR 2.0.2 but unfortunately since that particular version the algorithm has not produced correct result. For this image I used the Pfstools with
pfsinexr imagename.exr | pfstmo_mantiuk06 -e 1.0 -s 1.0 -v | pfsgamma -g 2.2 | pfsout imagename.png.
The result produced with the previous command is almost exactly the same as the result I use from LuminanceHDR 2.0.2 with contrast factor 0.8 and saturation factor 1.2. Luminance HDR 2.0.2 produces a bit more saturated image which I corrected in +GIMP by increasing the saturation by 25. Also the contrast of the Luminance HDR tonemapped image is a bit higher but that is negligible since in most cases some adjustment is made in any case.
Final image below has several the tonemapped images with different white balances combined. Combination processed in +G'MIC with anisotropic smoothing and overlaid over Hugin fused image with 66 percent opacity. In addition some local sharpening, contrast enhancement etc. edits were applied.
Now as HDR scenes go there probably are several potential points of HDR related discussion here.
1. Why would you use HDR on a scene like that?
2. It is way overdone and does not look natural!
Both of these statements are true for this image, please do not get offended :-) Overdone painterly look is intentional and desired effect for this image. Album has also the original for comparison. It gives a good impression of how the scene actually looked.

50 mm, f/5.6, ISO100
Three exposures with base exposure at 1/500 and +/-2 EV steps. Camera EV bracketing was -1EV, -3EV, +1EV. This leads to a very dark frame in any scene but especially so with this scene.
