How To Extract The Split-Tone Component of a LUT within DaVinci Resolve

Visual Math Part 3 – Manipulating LUTs using Layer Mixer transfer modes

One of the signature aspects of any LUT, especially a film emulation LUT, is its particular split-toning recipe: Its unique combination and strength of cool colors pushed into the shadows, and warm colors pushed into the highlights. Often this signature is the main thing we respond to when we decide to use a particular LUT. But that same LUT may also have additional contrast or colorimetry components which we don’t find desirable.

The traditional wisdom is, if we don’t like the totality of what a LUT is doing to our image then we either have to:

• Abandon the LUT and rebuild its split-toning by hand
• Or simply live with – or maybe counteract and minimize – what we don’t like about the LUT.

In this Insight, we’ll break down a technique for cleanly extracting the split-toning component of a LUT so that we can use it in isolation. We’ll do this inside DaVinci Resolve’s node tree, without using 3rd party software.
