Halftones - This type refers to the way gray levels are represented. Halftones are created through a process called dithering, in which density and patterns of black and white dots are varied to simulate different shades of gray. Although some resolution is sacrificed, halftones do adequately represent the appearance of gray levels. Grayscale - This is the use of many shades of gray to represent an image. Gray scaling is the process of converting a continuous-tone image into an image a computer can manipulate.
