10,500 feet is way the heck up there!

more pixels simply means you get to crop more of the original
picture. I'm still happy with 2.1 MP.

More pixels means more detail captured so that *when you crop* you still
retain a good quality picture.

I used to have a 2.1mp but I found that cropping more than half the
picture would result in a remaining picture that was too grainy. Having
more megapixels means having more cropping options for those times the
subject was too far away.

"Grainy" describes film. (grains of silver-halide crystals)

"Pixilated" describes digital images. (little square elements, pixels,
that make up the ccd image sensor)

Uh... Pixilated looks grainy to this uneducated, amateur photographer when
the picture is printed out.

But, if it makes you happy I will try to remember to use the technically-
correct term in future posts. :-)

What you're most often actually seeing that looks sort-of like film
grain in digital photos is CCD noise. "Pixelated" tends to mean you
can see all the pixel boundaries, which dosn't happen with modern
techniques (bicubic interpolation and such).

(And there does seem to be a word "pixilated", but it means
"whimsical, prankish, behaving as if mentally unbalanced, very
eccentric", deriving from "pixie", and doesn't seem to have anything
to do with picture elements).

I'd venture to guess that "grainy" is going to hang around in the
language to describe that appearance of digital photos.

Not really.

Digital pictures have both "grain" and "pixelation". As David notes,
"pixelation" refers to a very specific situation, in which the pixels are
large enough to differentiate. You can still get "grain" in a digital
photo, when there is not enough light to take a good picture and noise
starts taking over the CCD's response.

What Peter was referring to is "pixelation", but it's incorrect to say that
there's no such thing as "grain" in digital photography. There is, it just
doesn't come from literal grains of crystals in the film.
