That thought occurred to me, that the differences between CRT and LCD/LED
monitors might be part of the problem: creating the image on one type of
monitor, but viewing it on another. Years ago, I bought an LCD monitor-- but
took it back within days, as its color rendition/contrast were just too...
'different'... from what I was used to on my CRT.

I was wondering about that, too-- even whether my .jpeg screenshot image here
might look different (brighter) on other peoples' monitors than my own!

Posting .png images is something I rarely do (if ever?); I should do a test and
upload a .png here, to see if the *posted* result matches its original
appearance on my system. (But more importantly, to see if its tonal range
matches the 'overall appearance' of other .png's posted on the newsgroup.)

The last POV-Ray image I made and uploaded was my 'matchmoving' experiment, as a
..jpeg-- found here...

On my own system, that one looks identically the same on the newsgroup page (and
as a download) compared to my original. But does it possibly look 'washed out'
on your monitor (and/or on LCD monitors)? That's a subjective question, of
course, but it would be helpful for me to know.
