Blue noise dithering aims for a pattern whose frequencies resemble film grain: minimal low-frequency structure, so dots are distributed in a way that avoids clumping and visible regular patterns. That makes it one of the most visually pleasing options for photographs and for laser engraving where you want a natural, non-directional texture. It is often preferred when other algorithms produce visible worms, bands, or a mechanical look. If you are engraving photos on fine materials and want a premium, grain-like result, blue noise is worth testing.
