Halftone

In addition to the black and white display, Halftone
simulates gray scale by using different size of dots.
Particularly when you view the image at a certain
distance, it looks very closely like a gray image yet it
consumes the least disk space.    Halftone is the
picture that we usually see in newspapers or
magazines.    Since Halftone is one type of black
and white image, the disk space required to save a
halftone image is 1/24 of that required to save a 24-
bit true color image.
