Prompt
Apply a Floyd–Steinberg Dither effect, converting the image into pure black and white with fine, irregular single-pixel texture. Recreate shading through locally distributed dots and subtle directional wormlike patterns rather than repeated grids, preserving readable contours without gray pixels or smoothing. Keep the original subject and composition.
02Dithered CatA close-up of a cat's eye and fur rendered in monochrome. The fine, irregular grain creates the illusion of gray tones using only black and white pixels distributed via error diffusion.Conansc · CC BY-SA 4.0 · Wikimedia Commons033 birds on a fence in VGA 640x480 2-colorThree parrots perched on a chain-link fence overlooking a street. The two-color quantization uses Floyd-Steinberg dithering to represent depth and complex textures without the repetitive patterns seen in Bayer dithering.LoganDeveloper · CC0 · Wikimedia Commons04RGB 24bits palette sample image - 3-bit RGB - 300x zoom - no smoothingA zoomed-in view of a colorful parrot processed with a 3-bit RGB palette. The individual colored pixels are scattered to blend transitions, demonstrating how quantization errors are passed to adjacent pixels.RGB_24bits_palette_sample_image_-_3-bit_RGB.png: *RGB_24bits_palette_sample_image.jpg: Ricardo Cancho Niemietz (talk)

The diffusion of 1-bit color values creates smooth tonal gradients without ordered geometric patterns.Luc Viatour (photo); processed for the Atlas · CC BY-SA 3.0 · Wikimedia Commons06Floyd–Steinberg Dither, applied to “Household utensils - artwork - Malsch 01”Utensils hanging from a tree are rendered with a scattered dot distribution. This error diffusion technique maintains the luminance of the blue sky using an irregular pixel arrangement.H.

Golden Gate”The yellow Canna flower petals exhibit high-frequency, randomized grain. Quantization errors are pushed to neighboring pixels, creating the appearance of continuous color through a dense stipple effect.Michael Gäbler (photo); processed for the Atlas · CC BY 3.0 · Wikimedia Commons
