There is also the DNG Profile format (.dcp). Some converters will convert CUBE to DCP, and then DCP to XMP. This is an extra step, but DCP files are actually more scientifically accurate than standard XMP Presets for color matrix transformations.
If you are a professional printing photographer, you might want to convert-cube-to-dcp first, then install that DCP into Lightroom (which treats it as a Camera Profile). Lightroom internally uses XMP to reference that DCP, but that is an advanced workflow beyond the scope of this basic conversion guide.
There is no "Save As" button in Windows Explorer for this task. You need specialized tools. Here are the three most reliable methods.
In modern data and digital asset management workflows, you may encounter a niche but important requirement: converting a Cube (e.g., OLAP cube schema, data cube, or semantic cube definition) into XMP (Extensible Metadata Platform) format. While these two structures serve different primary purposes — cubes for analytical data modeling, XMP for metadata embedding in media/files — the conversion can be useful for:
This post explains the why, how, and code example for such a conversion.
A major challenge in Cube-to-XMP conversion is the Input Color Space Mismatch.
After running the tool, verify that the conversion was successful:
The .cube format is the industry standard for sharing color grading data. It is human-readable ASCII text.
The ability to convert CUBE to XMP bridges the gap between professional video grading and RAW photo editing. While no automated tool is mathematically perfect, modern converters (Photoshop ACR, Lattice, and LUTCalc) get you 95% of the way there.
Summary Checklist:
Now you can enjoy your cinema-grade LUTs directly in Adobe Lightroom. Happy grading.

To convert a .cube (LUT) file to an .xmp profile for use in Adobe Lightroom or Camera Raw, you essentially create an "enhanced profile" using Photoshop. While there isn't a direct "save as" button, the standard method involves a hidden modifier key within the Camera Raw filter. Standard Conversion Process (Adobe Photoshop)
This method transforms the color data of a LUT into a profile that Lightroom can recognize in its Profile Browser.
Open an Image: Open any photo in Photoshop (preferably a RAW file for better accuracy).
Converting a .cube (3D LUT) file to an .xmp profile is a common workflow for using cinematic color grades in Adobe Lightroom or Camera Raw. How to Convert .cube to .xmp
The most reliable way to perform this conversion is by using Adobe Camera Raw (ACR) through Photoshop, as Lightroom uses .xmp files to wrap LUT data into selectable profiles.
Open Adobe Camera Raw: In Photoshop, go to Filter > Camera Raw Filter... (or open any RAW file).
Access the Preset Creation: Navigate to the Presets tab on the right sidebar and click the three dots (...) or the New Preset icon while holding Alt/Option. Create Profile: In the "New Profile" dialog: Name your profile. At the bottom, check the box for Color Lookup Table. Select your .cube file from your computer.
Save: Once saved, Photoshop generates an .xmp file containing the LUT data. Where to Find the Converted File
Once created, the .xmp file is typically stored in the following directory:
Windows: C:\Users\[User]\AppData\Roaming\Adobe\CameraRaw\Settings
macOS: ~/Library/Application Support/Adobe/CameraRaw/Settings Alternative: Direct Import in Lightroom
Recent versions of Lightroom Classic allow you to import LUTs directly, which automatically handles the conversion: Open the Develop module.
In the Basic panel, open the Profile Browser (four-square icon). Click the + icon and select Import Profiles.
Select your .cube file. Lightroom will convert it to an .xmp profile for you. Key Limitations
RAW vs. Non-RAW: Some converted profiles may only appear when editing RAW files unless the "Treat as Raw" option is toggled during creation in ACR.
Metadata: Automated scripts (like Python's ET.SubElement) can be used to manually inject cube metadata into an XMP structure for advanced developers.
Here’s a technical write-up for convert-cube-to-xmp, a utility (or conceptual process) that transforms 3D LUT files from the .cube format into Adobe’s .xmp format (often for camera profiles or lookup tables in Lightroom/Photoshop).
