Thanks. And this is another beautiful landscape. But the dark shadow
areas are purple, instead of black. At this reduced early evening or
late afternoon brightness, the shadows would be black, I think. But
otherwise: woooww!!! :-)

I'm sorry, but beside the top right cloudless part of the sky, there aren't any
purple pixels (less green than blue / red). I searched several minutes with
photoshop.
Most probably it's an optical illusion, because intuitively I thought you were
right.
I admit, the shadows of this test render don't seem to be dark or structured
enough, but this is due to insufficient radiosity settings.

As long as there's any trace of blue in the sky above, or any visible
clouds, you can expect shadows to be non-black.
As long as there are any illuminated mountain tops nearby, you can
expect shadows to be non-black.
Heck, even on the moon, where the surface has an albedo of no more than
5%, you can expect shadows to be non-black.
Also, make sure that your display is properly calibrated. If it isn't,
judging the appearance of images by such details as brightness of
shadows, overall hue, etc. is moot.

Yes, the fault might be on my side: I am using, unfortunately, one of
these flat-screens. If you watch from a slightly wrong angle, what is
supposed to be dark appears less dark but in a lighter and unrealistic
(in front), and it looks okay. Sorry. I should continue to use my older
large regular monitors... :-)
I mean it, no joke.

The problem isn't the flatscreen /per se/; some are good, some aren't.
It depends on the exact variation of the LCD technology involved.
My primary display is pretty good, it's a 24" 16:10 EIZO with inbuilt
calibration and a horrible price tag, which gives a very homogenous
colour representation across the entire screen even when I move my head
around (within reasonable limits). My secondary display, on the other
hand, is rather poor in comparison, being a 24" 16:10 EIZO as well but
with a much more affordable price tag; horizontally the colour
representation is barely uniform when sitting perfectly centered, and
vertically hues differ across the screen no matter where I place my head.
So it's really a matter of getting what you paid for. But yes, in terms
of colour management good old CRT displays still win over most anything
LCD-based. I wouldn't want to burden my desk with two 24" devices of
that type though.
Also, genuine OLEDs (as opposed to LCDs with OLED-based backlights) are
an entirely different matter; I'd expect them to be about on par with
CRTs when it comes to colour stability (in space, that is; they do
degrade over time, probably more so than CRTs, so occasional calibration
would seem mandatory).

Magnificent images!
Thank you and a happy good year

Yes. And what most people don't know, is that older CRT monitors display
many millions of colors, while LED flatscreens display only several
thousands.
As graphic designer, I still keep my older but better CRTs... :-)

As long as you don't have to keep an eye on your electricity bill, they
are fine... but they are also very bulky, especially those 19-, 21- or
23-inch behemoths capable of display really high resolutions!
Currently, I'm on a retrocomputing trip and thus about to build myself a
386, 486 or first generation Pentium computer, as a monitor I would like
to choose a 14- or 15-inch CRT, any larger one would be overkill for
MS-DOS and also not fit into my shelf...
See you in Khyberspace!

Will you be doing your own mainboard layout? }:->

No, by "building" I meant "assembling from existing parts", not
"re-designing from scratch" - too bad I'm not a semiconductor company!
But believe it, nowadays those old computers are well-sought vintage
objects! You may find a 386 system announced for a cool 300 euros - very
unlike the 1990s and early 2000s, when you even found them on piles of
bulk trash!
See you in Khyberspace!
