What is dithering?

Dithering is an image processing technique that uses patterns of pixels to simulate colors and gradients beyond a limited palette. It creates a textured, retro aesthetic common in early digital art and print media.

What is a halftone effect?

Halftone recreates images using a grid of dots of varying sizes — the same technique used in newspapers, comic books, and screen printing. Ditther lets you control dot size, density, and blending in real time.
