HOW TO USE THE RETRO DITHER FILTER STUDIO// DIRECT WORKFLOW
GUIDE
1

Upload an image or drop it directly into the studio workspace.

2

Select a dithering algorithm (Atkinson 1984, Floyd-Steinberg, Bayer 4x4, Bayer 8x8, Halftone).

3

Pick a retro hardware color palette (Macintosh 1984, Game Boy, OP-1, Cyberpunk Amber) or custom colors.

4

Fine-tune contrast, gamma, sharpness, blockiness, CRT scanlines, and aspect ratio framing.

5

Compare with multi-mode split view (vertical, horizontal, dual view, hold to peek) and export in PNG, JPG, or WebP.

FAQ

What is Atkinson dithering?

Developed by Bill Atkinson for MacPaint in 1984, Atkinson dithering distributes 1/8th of the quantization error across 6 neighboring pixels, preserving high contrast and crisp edges.

Are my uploaded images sent to any server?

No. The image never leaves your device. All dithering algorithms run entirely inside your browser memory.

A Technical Deep-Dive into Retro Dithering Algorithms: Floyd-Steinberg, Atkinson, and Bayer

Learn the mathematical foundations of spatial error diffusion and ordered threshold matrix dithering that defined the visual aesthetics of the Macintosh 128K and Game Boy.

Key Technical Takeaway:

“Dithering simulates continuous tone gradients on displays with severely limited color palettes (such as 1-bit monochrome).”
