Apple Log is an AVFoundation capture colour space with BT.2020 primaries and an Apple-defined log transfer (iOS 17.0+); Apple Log 2 uses Apple Gamut primaries (iOS 26.0+) and, when active, deactivates other outputs on the same session. Final Cut Pro offers Camera LUT choices that convert Apple Log and Apple Log 2 to Rec. 709 with Apple 3D LUTs, or None to turn log processing off.
