Curve
Curve
A curve that represents a mathematical function in 2D that takes and input and maps to an output.
Nodes that output this type
Curve Gamma
A gamma curve. The gamma parameter corresponding to y=x^gamma.
Curve Identity
An identity curve, y=x
Curve Pivoted Sigmoid
A pivoted sigmoid contrast curve that anchors at the pivot and smoothly compresses shadows and highlights, with a slope parameter controlling midtone contrast.
Curve S
An S-curve remaps values by anchoring contrast at a chosen pivot, increasing or decreasing midtone separation via slope, gently flattening the curve near black with toe to compress or lift shadows, and softly flattening near white with shoulder to roll off highlights, while keeping black and white fixed.
