9 months ago That's what a curve works. You can try the curve function in photoshop, it works the same. In darktable, you can choose centripetal spline to avoid that.

9 months ago Thank you. I just tried the curves in Lightroom and Gimp and they don't work the same way. I no longer have access to Photoshop, so I can't test this. The curve extends only within the nodes. In DT, the other modes mentioned or a little better, but there is still movement. I'm just curious what the motivation is for having values outside of the range we want to modify change?

9 months ago nonlinear curves results in nonlinear change of colors - also known as banding. Usually not intended… you may consult https://darktable-org.github.io/dtdocs/en/darkroom/processing-modules/curves/ for explanations of the modes
Describe the bug
When I put a node on the curve and pull down the part of the curve above the node moves up, like spaghetti.
Steps to reproduce
Open curves
Expected behavior
The node should fix the part outside of the modified section
