Depth of field is not limited by the resolution of the media, that's not
part of the equation.  It is limited by a somewhat arbitrary calculation
based on human visual acuity and some arbitrary viewing distance.  What you
are talking about is limiting the resolution of the MEDIA based on human
visual acuity, not based on DOF.  That is two different things.

You probably believe Nyquist has no role in all this...that in order to
RELIABLY capture something at the limits of human visual acuity, you would
have to sample at ~2x (in both directions) to ALWAYS capture, and then be
able to always display, at that limit of resolution.  Given that, your 6M
pixels would now be 24M pixels...

But again, I think using some arbitrary dimension for your claim is simply
silly, as I've said, the human eye has to scan that 10 x 10 anyway, so why
limit the area?
