A grayscale representation of encoding images at various bit depthsfrom the top: 1 bit, 2 bits, 3 bits, 4 bits, 5 bits, and 8 bits. Notice the banding at lower bit depths. The color transitions at the higher bit depths are much smoother. The printing process is not capable of reproducing gradients with more than8-bits. However, in a dark room using professional equipment, it is easy to demonstrate the difference between 8-bit and 10-bit gradients. | ||
