Histogram Normalise
Use a histogram to normalise the colours.
Histogram Normalise
Method #
This node uses a histogram to convert the image to greyscale, and normalise the output intensities to between 0-1. Useful for increasing the contrast in an image, or remapping the overall brightness range.
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.
Min Level Change the minimum level for brightness
Max Level Change the maximum level for brightness
