iPhone Apple Log → S-Log3 Conversion LUT

Bring Apple Log into an S-Log3 workflow

Apple Log does not respond like Sony S-Log3. Creative LUTs built for S-Log3 land too flat, too dense or with shifted colour. This conversion translates Apple Log / Rec.2020 into Sony S-Log3 / S-Gamut3.Cine, so any S-Log3 look, and any Sony camera in the same edit, behaves as intended.

It is built from Apple's published Apple Log specification and Sony's S-Log3 specification. No look, no tone mapping, no gamut compression. 18% grey lands on S-Log3 code value 420 and 90% white on 598, exactly where a Sony camera puts them. The same result as Resolve's Color Space Transform, in a file that works in every editor.

Included

• .cube, 65 points, for DaVinci Resolve and Final Cut Pro
• .cube, 33 points, for Premiere Pro, CapCut and LumaFusion
• .dctl for DaVinci Resolve Studio: exact maths without LUT interpolation, an exposure control in real stops, and S-Gamut3.Cine or S-Gamut3 output
• A short guide with camera settings and workflow

Best suited for

• iPhone 15 Pro and 16 Pro filmmakers who shoot Apple Log in the Camera app, Blackmagic Camera or Final Cut Camera.
• Mixed shoots next to a Sony FX3, FX30, FX6, A7S III or A7 IV.
• Anyone who owns S-Log3 creative LUTs and wants to use them on iPhone footage.

This is a technical conversion, not a finished look. It cannot change what the sensor, lens or light did, so exposure and white balance still need matching shot by shot.

For Apple Log only. Not for Apple Log 2 (iPhone 17 Pro), which uses a different colour gamut, or for HDR or SDR clips.
