Conversion Report: Cube to XMP

Introduction

This report outlines the process and outcome of converting a Cube data format to XMP (Extensible Metadata Platform) format. The goal of this conversion is to translate the metadata and structural information contained within a Cube dataset into a format that is widely compatible with various metadata management and processing tools.

  • Load your .cube LUT into the converter.
  • Set target profile type: DCP (Camera Raw/Lightroom) or XMP profile (Camera Raw Creative Profiles).
  • Choose bit depth and gamut settings (leave defaults if unsure; use 16-bit/High precision if available).
  • Export the profile. The converter will produce a .dcp or .xmp package and sometimes an .lrtemplate/.xmp preset.
  • Install the profile:

    Color Accuracy: Native Adobe tools generally provide the highest fidelity. Third-party converters can sometimes shift highlights or shadows if the mathematical interpolation isn't perfect. convert-cube-to-xmp

    However, the most accessible method for Adobe users is using Adobe Camera Raw (ACR) + Photoshop.

    1. Parsing: The software reads the .cube header to determine the LUT size (e.g., 65 cubes) and domain.
    2. Matrix Generation: DNG Profiles require a ColorMatrix and a LookTable. The converter calculates how the LUT modifies color values relative to the standard DNG color space.
    3. Hue/Saturation Mapping: The 3D LUT is mapped into the "Look Table" section of the DNG profile.
    4. Embedding in XMP: The profile data is written into the XMP file under the crs:CameraProfileRestriction or as a binary blob encoded in Base64.
