Lightroom XMP → Sony LUT Converter

Using the LUT

• The file: a 33×33×33 .cube (35,937 points) clamped to 0–1. The look is built with the renderer the preset pages use: an approximation, not Lightroom's full rendering.
• In the camera (User LUT 1–16), input S-Log3: Sony applies imported LUTs to S-Log3 / S-Gamut3.Cine, so this LUT decodes S-Log3 with Sony's published curve, converts S-Gamut3.Cine to Rec.709, maps it to a Rec.709 picture with a soft highlight roll-off, and then applies the look. Record in S-Log3 / S-Gamut3.Cine, pick the LUT, and either bake it in or use it as a monitoring LUT. Exposure and white balance still shift the result, and colors outside Rec.709 are clipped, so test it before a shoot.
• In your editor, input Rec.709: apply it to S-Cinetone or other Rec.709 footage in Catalyst Browse, Premiere Pro or DaVinci Resolve; it is exactly the preview. S-Log3 clips take the S-Log3 file instead.
