Saturation The strength or intensity of a color based on the degree to
which it lacks its complementary color. For example, a
strongly saturated blue would have little or no yellow (its
complementary color). A red with little saturation would
have a lot of cyan (its complementary color) mixed in, and
as a result, would look muddy or dark.
Sharpening Removes the blurred edges of an image by increasing the
contrast (distinction between dark and light tones)
between adjacent pixels.
TWAIN An industry standard for transferring information from an
image capture device (such as a scanner) to your
computer.
