WOW. That's one beautiful image Norbert! Bravo.
Going to sit back, drink a cup of coffee, and stare at it for a while.

Fantastic, would like to visit this place. Povray is surely amazing, well done.
Cheers

That is one truly impressive photograph. I can hardly wait to see your
render.
But seriously, you've outdone yourself here. Great job!

I would expect so. Real life does it linearly; it is our perceptions
that are non-linear. My response to a low contrast scene has not been
to fiddle with the assumed gamma, but to change the lighting environment.

Absolutely gorgeous scene indeed. While your "experiment" contains the
danger of never finishing scene building, it is absolutely essential for
reaching any level of perfection. I do something less extreme than you
myself, with the result that over the last couple of years my production
has dramatically fallen ;-) There are other reasons too for this drop
but those are coming from RL... Anyway, this is a landmark image.

I suppose continuous render or did you interrupt and continue (+c) a
couple of times?

I recognise that. ;-)

I can only approve.

Thanks! My thoughts go to the numerous who are threatened of losing
their livelihood because of covid19.

Indeed. So as not to hijack discussion of this absolute masterpiece, switching
to off-topic thread for this...

Like reducing the ambient amount.

Lol - in the case you wonder about where all the animals are, here is an image
with all the creatures...

Thank you - I can remember a guy many years before - he said, povray can depict
anything. I want to add - it's sometimes hard to know, what I want to depict.

In fact texturing was really simple. A finish like "specular 0.3 roughness 0.003
diffuse 0.6 ambient 0" worked with nearly all objects. When I used assumed_gamma
2.2 there was much more work to do :-)
The biggest change was to reduce the radiosity contribution of the sky.
Here I used rather extreme settings (at least for me) -
#version 3.7;
#declare RAD = 8;
global_settings {
assumed_gamma 1
max_trace_level 255
noise_generator 2
radiosity {
pretrace_start 0.08
pretrace_end 0.04/RAD
count 30*RAD
nearest_count min (20, RAD)
error_bound 3/RAD
low_error_factor 0.5
recursion_limit 1
gray_threshold 0
minimum_reuse 0.015
brightness 1
adc_bailout 0.005
normal on
media off
}
}
#declare skyf = 0.5;
light_source {
<0,0,40000> color srgb (<2.42,2.23,1.87>+2.173*0.3)*0.85
area_light <1000,0,0>, <0,1000,0> 5,5 adaptive 0 jitter circular orient
rotate <-47,-50,0>
}
sky_sphere {
pigment {
function {max (min (y, 1), 0)}
color_map {
[0.0000 srgb <212*skyf,221*skyf,239*(1+skyf)*0.5>/255]
[0.1029 srgb <219*skyf,229*skyf,244*(1+skyf)*0.5>/255]
[0.1512 srgb <233*skyf,241*skyf,250*(1+skyf)*0.5>/255]
[0.1949 srgb <223*skyf,239*skyf,252*(1+skyf)*0.5>/255]
[0.2444 srgb <201*skyf,227*skyf,252*(1+skyf)*0.5>/255]

[1.0000 srgb < 79*skyf,103*skyf,170*(1+skyf)*0.5>/255]
}
}
}

Thank you Thomas. Indeed there was this danger - but in the end it became clear,
that I want to improve by making other images. There is a subtle intuitive
voice, which guided me. I simply wanted to exclude superficial rational
reasoning...

No, I used my two machines - the first for doing all the changes and the second
one for rendering. The second machine with 64 Gb RAM is loud and can heat my
whole passiv house - so my window was wide open all the time since xmas ;-) .

My rational side says such things are and will be inevitable. Personally I
conducted some scenario exercises with similar topics in my compony and in the
beginning I was shocked by the outcomes - this pandemie can lend to very deep
economic recessions - and wars.
Times are becoming even more interesting (in the chinese sense - may you live in
interesting times)...
