You're missing the point.

Well, no.  It couldn't then and it can't now.  It equals it in size, but not
fidelity.  It simply can't, and doesn't.  Your sole criteria for image
"goodness" is sharpness, which is really a singular and mostly irrelevant
criteria for image fidelity (again, in this case).  I know you don't
understand that, and that is why we always butt heads on this.  To YOU it
looks better, by your criteria of observation, and I understand that, but
that that doesn't make it universally better, nor is your criteria the same
as everyone else's.

Who knows what you are comparing, Jerry, or what your criteria is...but for
sure, it's probably this mythical "sharpness".

> And there was no pixelation in the comparison prints I saw.

I'm sure there wasn't.  It was highly manipulated.

No.  The Foveon (at least the one we are discussing) is a THREE M pixel, not
9.  You are confused about what a pixel is and isn't.

And with great care, at least for the Foveon image.

You don't lose detail, you just don't get any more by upsizing.  If you take
two images.  One from a 3M pixel camera, upsize it to say 9 M pixels.  Then
compare it to a 9M pixel image, the 9M pixel image will have a lot more
detail.

Er, I probably could.  I do it all the time.  The issue is, if you don't
know what detail isn't there, you don't know that it's missing.  Sharpness
does not require detail, they are two entirely different things.
