Halftone
In addition to the black and white display, Halftone simulates
grayscale 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.
