Gaussian-ish distribution, maybe?

I must say that I find it rather comforting that in this reboot of the
Cold War franchise the country I live in does /not/ have /the/ front row
seat for a change.

Agreed. Neither was our second row seat, I mus say... I still remember
the cruise missiles business.

Agreed, without reservation ;-) I have no clue as to why my (older v5.0) of
Photoshop would create such an *extremely* wrong gamma encoding. I knew it was
somewhat wonky (from reading about its possible PNG problems years ago)--but not
to that degree!

I assumed that just about all relatively recent flat-panel monitors are
factory-preset gamma-wise to show JPEGs correctly. I guess that has always been
my own rather dubious 'benchmark' for using JPEG vs. PNG. (And I'm coming to
realize that my own doubts about PNG actually owe their origin to my crappy
version of Photoshop! I've been using it WAY past its 'expiration date'. But the
'pain' of dealing with PNGs there is hard to forget.)
I now understand the newsgroup 'problem' I encountered with my
originally-uploaded Photoshop'd PNG file--that crazy gamma 4.4 image: The
'small' preview in the newsgroup is modified (for want of a better term) to look
'correct' no matter what it's gamma might be (or when there's no intrinsic gamma
at all, in the case of JPEGs); whereas the 'larger' preview (the much darker
one, in my case) shows the ACTUAL/awful gamma encoding of my image. And I was
assuming the opposite!

I once did a scene with a daytime macro: the time could be specified (1,
2, ..., 24) and the sky colors and sky illumination would change
accordingly as well as building illumination. For now, you could work
with just "Day" / "Night".

Pity us with our "Yes Mr President, no Mr President. How high should I
