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]

}
}
}

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)...

Hi Norbert,
3 months well spent!
You really are the master of this kind of nature image, certainly what I
inspired to achieve on my attempts but never had the skill and patience to
achieve this level of detail.
Glad you provided the extra large image and also the animals only version so I
could zoom in and spot them. The one I still couldn't see was the Squirrel but I
think even when you don't see/notice these they still add something to the
image.
great work as always.
Sean

Hi Sean,
the squirrel was introduced in february after several previous relocations. But
a later tree needed for shadows hides it now.
Like other meshes I downloaded a free low polygon model without textures and
used the nice displacement feature of Poseray.
Displacement was used on all visible trees and several animals to prevent smooth
shadow borders.
Regarding skills - I envy your modeling and texturing skills since your late
IRTC entries and of course Povcomp. In comparison I'm only good at throwing
objects together in a more or less pleasing manner...
Hopefully we can see more new images from you.
Regards,
Norbert
