Dither
Updated: 24 Feb 2025
Add a dithering effect to the image.
Dither
Method #
This node applies a dithering effect, which attempt to simulate the creation of new colours in an image by creating a varying pattern from the colours available. Useful for breaking up banding in an image, or adding a pixelated pattern. Each pattern generated uses a different bit depth, and a different method for generating the dithering pattern.
Parameters
These properties control the core behaviours of the node.
Parameter Details Active
Enables or disables the effect. Disabling the effect means it will no longer compute, so disabling a node when not in use can improve performance.
Blend Amount
Changes the opacity of the new effect over the original image.
Blend Mode (RGB)
Change how the generated effect blends with the parent image RGB.
Blend Mode (Alpha)
Change how the generated effect blends with the parent image alpha.
Affected Channels
Toggle which of the RGBA channels are affected by the effect.
Mode
Which method of dithering should be used.
Inputs
These properties control the core behaviours of the node.
