Greyscale
In photograph, computing, and colorimetry, a greyscale or greyscale image is one in
which the value of each pixel is a single sample representing only an amount of light,
that is, it carries only intensity information. Images of this sort, also known as black-
and-white or monochrome, are composed exclusively of shades of gray, varying
from black at the weakest intensity (0) to white at the strongest (255).
