Grayscale: Standards, Converting color to grayscale & Numerical representations

In digital photography, computer-generated imagery, and colorimetry, a grayscale (American English) or greyscale (Commonwealth English) image is one in which the value of each pixel holds no color information. Pixel values are typically stored in the range 0 to 255 (black to white).
