Pixels

In computer terms 1K is not 1,000 bytes but 1,024 bytes. How many
pixels are there in 1 MP. Is is 1,024,000?

It depends whether you are buying or selling! Whichever gives the bigger
number when you are selling is likely to be used, so 1000 x 1000 pixels =
1MP.

For example, I have seen CF cards where "128MB" actually meant 128,000,000
bytes, or 122MB to you and I....

No, pixels aren't measured like bytes.

IMHO I wouldn't trust a "K" unless it's used specifically with computer RAM.
Today, 1K has been loosely tied to the number 1000. You will find that when
you actually investigate how many megapixels a camera has it is not exactly
defined by K, or even a million, but it's close enough. It's more like
buying a home that lists for $250K, or a car that has 100K miles on it.
Don't do the math. Just take it for what it's worth.

It should be 1024 X 1024 = 1,048,576 if computer terminology is followed. The diference
from 1,000,000 doesn't really matter in practical terms. And the number of pixels in a
digitla photo is usually a bit less than the number of individual sensors on the image
sensor. A few cameras actually interpolatre many extra pixels in the image, which many of
us regard as misleading the public about their cameras.

Not usually. Marketing types like to exagerrate as much as possible,
so you'll find that one megapixel is typically 1,000,000 pixels.
Maybe even slightly less. For example: The Canon Digital Rebel takes
pictures of 6,291,456 pixels. That's advertised as being 6.3MP.

But it doesn't really matter. Even a 10% difference in the number of
pixels isn't going to have any appreciable effect on your photos. Far
more important are all of the other things that go into a camera.
