Grayscale
a black-and-white form of continuous tone imagery. Unlike bitonal images, where one two tonal values can be described, grayscale images are (typically) composed of 256 shades of gray (28 or 8-bit), varying from black at the weakest intensity to white at the strongest. High-end scanners are capable of capturing 12-bit (212) and 16-bit (216) grayscale. Grayscale images are also called monochromatic, as they only capture one channel of color.
