No your'e not casting pearls....unless they are of wisdom! ummm, thought
that might be nice.

Not sure how your maths argument stands up. To me, the more pixels to cover
the area, the more DETAIL one achieves. If one copmpares to film (Urrg, NO,
I will NOT call film 'analogue'!) then, fast negative film, especially b/w
returns much noise and less detail then slow colour film. The answer is of
course the number of silver halide crytals and their responsive nature.
Colour slide film of good quality is slow, but within the same frame-size,
carries far more detail, to the degree that via a projector you can enlarge
to huge size and maintian a sharp image.

Low resolution digitail pics will pixalate badly when enlarged. If both a 3
megapix and 5 megapix cam have the same size ccd area, then surely the 5
megapix will carry more detail and permit larger blowups MAINTIAINING
detail, not just STRETCHING the image.

But, maybe as you say, at 6x4 who would see the difference?

Just some thoughts.
