T3D Re: digital camera resolution

[bercov@xxxxxxxxxxx (John Bercovitz)]

Just taking the base numbers, I think there is something fishy here.
Supposing we accept the guy's 40 lpmm in a 35 mm camera (fair if you
have any depth of field) then the image has 24*36*40^2 or 1,382,400
pixels.  If we take a 640 x 480 camera and throw in Nyquist (you have
to have two pixels to image one black and one white bar) you have 340
x 240 or 81,600 pixels of the same nature as the 35 camera's pixels.
(Probably I should have done this the other way - multiplied the 35
camera's resolution by two to get the digital camera pixel equivalent.)
