When talking about grayscale images, we imply “black-and-white”, though this is not really true. In true black-and-white images there are only two real shades – black and white, while grayscale images contain several shades of the gray color. Digital grayscale images are typically 8-bit, containing up to 256 shades of gray ranging from 0 (black) to 255 (white). Instead of color information, the image file stores levels of brightness or intensity. Grayscale images are differentiated from other color images, because the intensity of the red, green, and blue components are all of equal intensity in RGB space. Instead of specifying 3 various intensities for full color images, dealing with grayscale we only have to specify the intensity of each pixel. Images of any color can be turned into grayscale TIFF via the command-line of ImageConverter Plus. Situations when grayscale images are a preference are numerous: they are used when color printing is unavailable and in desktop publishing in general; lots of display and image capture hardware support only 8-bit images; last but not least, why use something more complex, when a grayscale image can be sufficient for most tasks.
