Import photoshop curves?

On one of the Unity videos I saw Aras mention a way to import Photoshop curve data to apply to a scene, but it is not clear how to do this in the video. Can someone please explain how this is done?

Assuming you’re using ColorCorrectionEffect from the Pro shaders, just copy the “color correction ramp” into Photoshop, and apply the curves you want, then save it again. The ramp file in Pro Assets is a perfectly linear ramp, so any curves you apply to it will be reproduced exactly when applied using ColorCorrectionEffect.

Ah ok, that makes perfect sense. Thanks!
