Digital BW, The Print

Austin, I don't care about arithmetic, numbers or bayer patterns. I only
can tell you what my eye sees. That's
good enough for me.  Before I got my D60 camera, many people said it
couldn't possibly equal film at 12x18 inch film print. I think you were
among them. Well it can. And I will not get into a debate with you as
you will only say that's impossible. Sorry, but it is possible and my
prints prove it to anyone who has seen them.

And there was no pixelation in the comparison prints I saw. Remember it
was a comparison between a 9 megapixel chip (foveon) and a 6 megapixel
chip (Canon). I assume these pictures were upsized with General Fractals
or some other program like it. I always upsize mine to 240 DPI at ouput
resolution for photographs. I know you say they couldn't possibly be as
good, I must lose all kinds of detail when I do this, but I don't.
Nobody could tell that if they were upsized or not. I'm only speaking of
12x18 inch prints on 13x19 inch paper here. Not billboards.

The foveon is effectively NINE megapixles Austin, not  3. The Canon is SIX.

That would be 1400 pixels of image data over a 30 inch span...or

Austin I would never send a 46 DPI image to the printer. and the foveon
is NINE megapixels. You know this.
