How to install and use a .cube LUT in DaVinci Resolve

You have a .cube file and footage in DaVinci Resolve. Installation is genuinely simple; the mistakes people make are almost always about where in the pipeline the LUT is applied, not the file itself.

Installing the file

The easy way (Resolve 17+): Project Settings → Color Management → "Open LUT Folder", drop your .cube file in, then click "Update Lists". The folder locations, if you'd rather go direct:

OSPath
macOS/Library/Application Support/Blackmagic Design/DaVinci Resolve/LUT/
WindowsC:\ProgramData\Blackmagic Design\DaVinci Resolve\Support\LUT\

Subfolders you create there become categories in Resolve's LUT browser.

Three ways to apply it

The node-order rule

A display-referred LUT (built from normal sRGB images — screenshots, photos, exported frames) expects display-referred input. Apply it after your conversion from camera log, and after exposure/white-balance correction. The clean pattern is three serial nodes: normalise → correct → LUT. If the LUT is first and your colour-space transform second, the maths runs on the wrong values and nothing downstream can fix it.

A LUT bakes its look over whatever it receives — so exposure fixes belong before the LUT node, and any creative trim you still want belongs after it. If you find yourself fighting the LUT with big corrections after it, the input wasn't normalised first.

Checking the result

Toggle the node on and off. The look should change; the image structure should not. Banding in skies or posterised shadows that appear with the LUT signal either a low-resolution LUT (17³) or a poorly built one — see how 3D LUTs work for what separates good LUT files from bad ones.

Tonemara does all of this in your browser in one click: drop a reference image and your own photo, preview the match free, and export a 33×33×33 .cube LUT plus a Lightroom-compatible .xmp preset. Your images never leave your device.
