GLOSSARY
RESAMPLE To change the number of pixels in the image. If pixels are
discarded when shrinking an image, it is called resampling
down. If new pixels are created in an image, it is called
resampling up (p. 59).
RESOLUTION The number of pixels in a given area of the image; such as
pixels per inch or pixels per centimeter. High resolution is the
term for an image with a lot of pixels in a given area. Low
resolution means there are not many pixels in a given area.
RGB Red, Green, and Blue. These are the colours of the three
channels that make up the scanned image. Monitors use red,
green, and blue phosphors to create the image you see on the
screen.
SHADOWS The dark areas of an image.
