Free Nuke 14 Script: Underwater Look with Curve-Based Depth Treatment (Split The Diff)

Overview

Sebastian Schutt of Split The Diff shares the script behind his underwater look, where red light diminishes first with distance and blue lasts the longest. Instead of a Grade node driven by a normalized depth pass, the setup uses the ColorLookup node as a lookup table so that each color channel gets its own curve over depth, plus a hue-based depth treatment.

The post also shows how to add and delete curves with Python. The zip holds UnderwaterLook.nk, saved in Nuke 14.0, as a free direct download.
