Atlas demonstration: the free source photo and the computed Atkinson Dither. A group of horses stands together in an open field under a bright sky. The algorithm transforms the animal forms into a dense field of black and white specks that simulate soft shading.Image: Samantha Scholl sauriel · CC0 (via Wikimedia Commons), processed for the AtlasView source ↗
Prompt
Apply an Atkinson Dither effect using pure black and white pixels, with compact dot clusters, open white highlights, and bold dark shadow areas. Replace smooth shading with airy, high-contrast pixel patterns that retain less midtone detail, avoiding gray pixels and regular checkerboard screens. Keep the original subject and composition.
You see ahigh-contrast image where [smooth shading1]is replaced by distinct clusters of tiny monochrome dots.
Principle
It turns pixels into [pure black or pure white]. It then shifts afraction of the resulting [quantization error2]to nearby unvisited pixels.
Try it out
Look closely at how midtones display distinct speckled patterns while pure highlights and deep shadows remain solid.
Classification
Calculated image processing result.

02Atkinson Dither, applied to “Coffee, notebooks and pen (Unsplash)”A top-down view captures an open notebook, a pen, and a cup of coffee resting on a wooden table. Stippled patterns define the grain of the wood and the gradients of light hitting the paper surfaces.Freddy Castro readysetfreddy (photo); processed for the Atlas · CC0 · Wikimedia Commons03Atkinson Dither, applied to “People watching 1 (Unsplash)”The ocean tide rolls in over a sandy beach populated by small figures of people. Large clusters of dots create the appearance of undulating gray waves while preserving the silhouettes of the beachgoers.Jarrett Kow haskel (photo); processed for the Atlas · CC0 · Wikimedia Commons04Atkinson Dither, applied to “Steel Bridge Below (Unsplash)”This perspective looks directly upward from beneath the massive iron structure of the Eiffel Tower. High-contrast monochrome rendering highlights the geometric complexity of the girders through sharp black shapes and fine-grain error diffusion.valor kopeny valor (photo); processed for the Atlas · CC0 · Wikimedia Commons05Atkinson Dither, applied to “Crayons beside child coloring (Unsplash)”The composition features a small container of pens or tools in the foreground set against a soft, organic background. The process translates the smooth photographic bokeh into a textured, mechanical-looking distribution of pixels.Aaron Burden aaronburden (photo); processed for the Atlas · CC0 · Wikimedia Commons06Atkinson Dither, applied to “Elegant boardroom (Unsplash)”A modern conference room is shown with a long table, ergonomic chairs, and large floor-to-ceiling windows. The technique is clearly represented through the stippled patterns on the floor and the varied densities of black dots defining the shadows on the chairs.Benjamin Child bchild311 (photo); processed for the Atlas · CC0 · Wikimedia Commons07Atkinson Dither, applied to “Desert Sunrise (Unsplash)”A mountain range is silhouetted against a bright, hazy sky during a sunset or sunrise. The transition from light to dark in the sky is achieved through a precise scattering of monochrome dots that simulates a smooth gradient.Red Morley Hewitt redvers (photo); processed for the Atlas · CC0 · Wikimedia Commons08Atkinson Dither, applied to “Shahdad desert (Unsplash)”A lone figure with a backpack and hat stands in a vast, arid landscape near a large rock formation. The grit of the desert floor and the shading on the hiker's clothing are meticulously rendered using the characteristic error-diffusion pattern.POOYAN ESHTIAGHI pyeshtiaghi (photo); processed for the Atlas · CC0 · Wikimedia Commons09Atkinson Dither, applied to “Winter (Unsplash)”A dense forest of leafless trees stands over a field covered in a light layer of snow or frost. The intricate branches and the texture of the ground are defined by a complex web of black and white pixels that preserves fine detail.Maarten Deckers maartendeckers (photo); processed for the Atlas · CC0 · Wikimedia Commons
