Use a .cube LUT without replacing your original

A LUT is a color mapping, not a photo and not an executable plugin. Neko Photo has a LUT panel with a .cube file browser and intensity control. 1. Open an image locally and keep its original file. 2. In a build with the LUT panel, browse for the downloaded .cube file. A 3D LUT must contain the declared number of RGB samples. 3. Start with reduced intensity. Compare shadows, highlights and skin tones; a LUT is not an exposure or white-balance repair. 4. Export to a new file when you are ready. Keep the original if you want to revise the edit. The original Gentle Warmth resource is a 17³ educational LUT. Its formula makes a mild warm shift. Its license is CC0-1.0. The portal verifies its checksum; it does not upload your photo or execute the file.
