Prompt
Apply a Bayer Ordered Dither effect using only black and white pixels. Replace smooth gradients with visibly repeating square threshold patterns, producing regular checkerboards and stepped tonal textures. Keep pixel edges hard, pattern spacing consistent, and outlines recognizable without blur or random grain. Keep the original subject and composition.
02Triple 1-bit to 3-Bit DemoFour versions of a parrot image show the results of 1-bit color channels. The grid-like patterns in the highlights and shadows demonstrate the mathematical regularity of an ordered threshold matrix.Luigi970p · CC0 · Wikimedia Commons032-bit pixel art balls X3A grid of spheres demonstrates various dithering densities. Several columns show the distinct checkerboard and cross-hatch arrangements produced by ordered Bayer thresholding.Dpla-fr · CC BY-SA 4.0 · Wikimedia Commons04Color dithering gradient pattern exampleA color gradient transitions from purple to yellow using a series of geometric pixel patterns. The progression clearly shows the different matrix levels used in ordered dithering.Gustavo Pezzi · Public domain · Wikimedia Commons05ZX Spectrum standard palette with 8x8 ditheringA series of horizontal color bars demonstrates 8x8 ordered dithering. The zoom reveals regular, repetitive pixel patterns used to simulate intermediate shades through a fixed threshold matrix.Dpla-fr · CC BY-SA 4.0 · Wikimedia Commons06Vollton halbton stucki2The central panel shows a gradient processed with ordered dithering. It displays a rigid geometric mesh of pixels that distinguishes it from the stochastic Stucki error diffusion in the third panel.Afrank99; M.G.Berberich · CC BY-SA 3.0 · Wikimedia Commons07AI illustration: A female portrait is displayed on a CRT monitor using a limited color palA female portrait is displayed on a CRT monitor using a limited color palette. The gradients are rendered through a distinct, grid-like threshold matrix characteristic of Bayer ordered dithering.Illustration generated for the Atlas (AI)
