Plot Curves Adjustment Layers
Parametric Curves lets you plot Functions inside Curves Adjustment Layers - that is, you can write your own maths to graph Curves.
Endless creative possibilities mixing Parametric Curves on top of Gradients, to create peculiar designs and bizarre patterns.
Use Curves applied to Gradients as source for Displacement Maps or Depth and Bump Maps to create impressive 3D objects.
