Threshold

Threshold

Limit the colour in an image.

image

Method #

This node limits the range of colour values in the image based on the luminance of each pixel. Useful for removing areas of an image which fall below a certain brightness level.

Parameters

These properties control the core behaviours of the node.

ParameterDetails
ActiveEnables 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 AmountChanges the opacity of the new effect over the original image.
Blend Mode (RGB)Change how the generated effect blends with the parent image RGB.
ThresholdChange the luminance threshold for the effect to apply.
Falloff RangeControl the falloff of the threshold edge.
Falloff PowerControl the strength of the falloff.
ModeChange how the threshold functions.
  • Above : Anything below the threshold is omitted.
  • Below : Anything above the threshold is omitted.
  • Band : Anything outside the middle values are omitted, within the range specified by the threshold.
Output ModeChange how the cut image outputs.
  • Colour : Colour is output along with the image.
  • Mask : A mask is generated based on the regions inside the threshold.
