Posterize

Quantize luminance into a flat color palette

Posterizing throws away the in-between shades and snaps everything to a small set of flat colors. Without smooth transitions you get bold, banded blocks — the silkscreen / propaganda-poster feel. Fewer colors, more graphic punch.

I. Made with Posterize

II. Everything else

Blob Tracker — Locks targeting marks onto what moves below
Contour — Detects edges with a Sobel filter and draws them as clean outlines
CRT — Puts the layers below on a tube screen — scanlines, phosphor and curved glass, or worn VHS tape
Dither — Ordered dithering of the layers below — into greys, its own colours, or a palette you pick
Engraving — Redraws the layers below as engraved line work — banknote portrait, cross-hatching or one spiral groove
Gem Smoke — A logo or word as clear glass with coloured smoke swirling along its walls
Glitch — Row displacement and scanline injection
Glyph Dither — ASCII/glyph rendering of the layers below, by brightness
Grain — Film grain noise, optionally animated
Halftone — Rebuilds the image as a rotated grid of ink dots, lines or squares
Heatmap — A logo, word or image seen through a thermal camera — a burning outline, a wide glow, a hot front sweeping across
Liquid Metal — Turns a logo or word into polished, slowly molten metal — chrome, gold, mercury
Paper Texture — Prints the picture onto a real sheet — fibres, tooth, crumples, folds and stains, lit from one side
Pixel Sort — Sorts runs of pixels by brightness into dripping streaks — the glitch-art classic
Pixelate — Snap coordinates to a coarse block grid
Subdivide — Break the layers below into blocks that keep splitting, by chance or by detail
Topo Lines — Draws contour lines through the layers below, like a topographic map of their brightness
