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

February 17, 2022

Learn how to isolate the color impact of a LUT from its luma component to craft the image to your preferences, all 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.

In This Insight

My goal with this Insight is for you to learn:

  1.  How to use the Color, Add, and Subtract modes of the Layer Mixer to isolate the desired components of a LUT.
  2. How to use multiple instances of a Shared Node to control the impact of the LUT on your final image.
  3. How to share the final results of your LUT manipulations with other members of the production or post-production team.
  4. How to reason your way through creative challenges, and implement solutions with the Layer Mixer and node connections.

    Great insight! I’d love to know where you got that 1D LUT. Most LUTs I find tend to have a color space transformation built in, which makes them kind of a bad candidate for this exercise.
