Well, this was my first experiment with a more complicated HDR scene
than just a box. And it seems that producing good HDR images with
PoV requires some experience than I already have.
The original LogLuv image did also store a so called STONITS information.
This can be used to calculated the physical brightness for each pixel in
candelas/squaremeter but this info was lost when transformating the image
to the radiance HDR format. But I'm not even sure if the stonits was
calculated correct. And as this image with the 'poor' radiosity settings
(samples 500, error_bound 0.3) took already about 3 days to render
on my old machine I am meanwhile a little bit bored in experimenting
with it. But for sure I will continue the work sooner or later (maybe
later, because I need a faster machine) so I have thought I do post this
little experiment to see if it somehow works for you.

And thanks a lot for trying it :)
