Dithering
ディザリング / 1960s– / 기법 / 디지털 이미지 기법
Dithering suggests unavailable intermediate colors by spatially mixing pixels from a limited palette; ordered matrices or error diffusion make both tone and a distinctive granular surface.
Two or more pixel colors mixed as checks or grain / High-frequency dots spreading around tonal boundaries / Apparent gradients made from a fixed palette / A pattern up close that becomes an intermediate color at normal distance

- 타이포그래피
- Use bitmap or simple sans type that remains intact at low resolution.
- 구성
- Build broad tonal fields but control diffusion around contours and copy.
- 재료
- Fix the palette first, then pass quantization error to neighboring pixels or place dots with a threshold matrix.
- 주의
- Adding monochrome noise is not dithering. The limited colors must approximate the source value.
