Grayscale Grayscale refers to an image that consists solely of shades of gray, ranging from black to white, without any color information. Grayscale images are created by representing each pixel in the image with a single value that corresponds to its brightness or luminance level. Higher pixel values represent lighter shades of gray, while lower pixel values represent darker shades of gray. Grayscale images are commonly used in photography, digital imaging, and printing to represent black-and-white photographs, illustrations, and text documents. Grayscale printing techniques, such as Giclée printing, allow for the accurate reproduction of grayscale images with smooth tonal transitions and fine detail. |
