Image dithering is a technique used to create the illusion of color depth in images with limited color palettes. By arranging pixels in specific patterns, dithering can simulate gradients and smooth transitions using only two colors - typically black and white.
The Floyd-Steinberg algorithm is one of the most popular dithering methods. It works by diffusing quantization errors to neighboring pixels, creating more natural-looking patterns. Our tool allows you to customize the error diffusion weights for unique artistic effects.
The four weight sliders control how quantization errors are distributed to neighboring pixels. Weight A affects the pixel to the right, B affects bottom-left, C affects bottom, and D affects bottom-right. Adjusting these values creates different dithering patterns and textures.
The contrast slider allows you to adjust the image's tonal range before dithering. Increasing contrast creates more dramatic black and white separation, while decreasing it produces softer, more subtle dithering effects.
Dithering is perfect for creating retro-style graphics, preparing images for screen printing, generating artistic effects, or optimizing images for display on limited devices. It's widely used in digital art, vintage computing aesthetics, and print design.
For optimal dithering results, start with high-contrast images or adjust the contrast slider. Experiment with different weight combinations - negative values can create interesting inverse patterns. Use the randomize function to discover unexpected artistic effects.
