Well... it looks fine to me, that's all I'm saying. ;-)

OK, well that's pretty weird. I wonder why they suddenly changed it to
48 kHz then...?

Not by a *long* shot! ;-)

Ah, OK. Spending 20 minutes waiting for Access to load each time I

Because Gnome does the same thing that AmigaOS does, and lighter WMs don't.

Microsoft Access for the AmigaOS was hugely popular, I suppose.

is blazingly fast. Clearly Windows is much faster than Linux."

Now you are an expert on window managers, I see.
Exactly what is it that Gnome does that no other window manager does?

Nope. But other database products were.
The real point is more that on a PC, just switching from one window to
another always seemed to take forever, whereas on an Amiga it was
instantaneous unless the machine was under heavy load.

OK, forget it. This conversation is over.

Except it clearly isn't impossible, because it was done. The way this
works is by using white balance. I've done it myself many, many times
with old photos in the GIMP.
But the sofa and the rug aren't exactly the same colour - the rug is
darker than the sofa (? looks like a chair to me). Adjusting the white
balance of the photo involves picking out something that actually is/was
white (like the white on the baby's shirt). That gives the computer a
reference to make the adjustments from. When photos age, they tend to
age consistently and the colours adjust with consistency. The computer
basically is doing an "undo" on the age effect applied by real life.

Yep, I remember selling the Amiga for Software Etc. - we had a local TV
station bring in their setup to do a demo. Pretty cool stuff.

Well yeah, OK, I rephrase: It defies explanation.

But surely no scanner on Earth has sufficient resolution that you can
amplify a signal by many orders of magnitude and not be swamped by
noise? The photo posted contains almost no blue whatsoever, so you'd
have to apply a ridiculous amount of gain to that channel...

See my explanation below. :-)

Except that's clearly not the case. There is blue in the photo, though -
that's clearly visible by looking at a breakdown of the RGB channels
using something like the GIMP. There's certainly more red and green in
the photo, but just look at the outfit the baby's wearing and tell me
there's no blue there - on the shoulders and the matching "pants" (don't
know the word for that part of the outfit). Along the baseboard to the
left of the chair - that's a purplish colour there, blue is a component
of that.

Yeah, and they are comparable like Blender and Paint are completely
comparable.

It is not only the number of colours, There was also the hardware to
animate them at 25 frames per second.
