Everything you need to know about Blue Noise Dither
Blue Noise Dither converts your image to black and white using a special dithering technique that produces an organic, visually pleasing pattern. Unlike regular noise, blue noise has no visible clumping or repetitive structure, resulting in a natural-looking stipple effect similar to hand-drawn pointillism.
Parameters
- Scale
Controls the size of the dither cells. Smaller values (0.5–2) create fine, detailed patterns with tiny dots. Larger values (16–64) produce a coarser, more blocky appearance. - Seed
Changes the random pattern used for dithering. Different seeds generate different noise distributions while maintaining the blue noise characteristics. Useful for finding a pattern that works best with your specific image. - Mix
Blends the dithered result with the original image. At 0, no effect is visible. At 1.0, you see the full black and white dither. Intermediate values create a subtle textured overlay.
Tips
- Use small scale values (1–3) for print-quality halftone effects
- Great for creating retro, newspaper-style, or artistic poster looks
- Try different seeds if the pattern creates unwanted artifacts on specific image features
