Error diffusion

A dithering family that passes the difference between an original tone and its black-or-white decision into neighboring pixels.

In the workflow

Why Error diffusion matters

Floyd-Steinberg, Jarvis, Stucki, and Atkinson use different neighborhoods and weights, producing different dot fields.

Practical check

How to evaluate it

Zoom into smooth gradients and edges to see how error is distributed. Compare that texture with an ordered method without changing the source or output dimensions.

Go deeper

Understand how one-bit dithering represents photo tones, how common algorithms differ, and how to choose without processing the image twice.

Prepare the pixels

Use the terminology in a real photo workflow.

Crop, tune, size, dither, and export a one-bit PNG on iPhone or iPad. Test the result on scrap with your machine and material guidance.
