Dithering
ディザリング / 1960s– / Technik / Digitale Bildtechniken
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

- Preserving photographic tone on low-color displays and e-paper · Using the grain of early computer images as deliberate digital material
- Typografie
- Use bitmap or simple sans type that remains intact at low resolution.
- Komposition
- Build broad tonal fields but control diffusion around contours and copy.
- Material
- Fix the palette first, then pass quantization error to neighboring pixels or place dots with a threshold matrix.
- Zu vermeiden
- Adding monochrome noise is not dithering. The limited colors must approximate the source value.
