Log → Rec.709 Conversion Apple Log .cube 947.8 KB

Technical Apple Log / Rec.2020, iPhone 15 Pro and later to Rec.709 conversion. This is a neutral normalisation, not a creative look — it puts log footage on a correct display-referred starting point so you can grade from there. Built from the published transfer function and gamut matrix, with a highlight shoulder so over-white detail rolls off instead of clipping. 33×33×33.

What this LUT does

Measured from the file itself: it adds contrast (about 51% steeper through the midtones); pushes saturation up around 46%; takes blacks to zero; leans warm shadows. It clips at least one channel on a saturated highlight, so give stage lasers and LED walls a look on the slider above before committing.

How this was measured: a 21-step neutral ramp and nine saturated probes are pushed through the lattice and compared with what went in. Contrast is the slope between 35% and 65% input; saturation is the mean change in distance from the grey axis; the cast is the direction a neutral input comes out at three heights. Rec.709 luma throughout — the same coefficients the previewer uses, so these numbers describe the image in the slider above.

Apple Log exposure: highest grey, least headroom

Apple Log puts 18% grey at 48.8% and leaves 6.06 stops above it, the least of eight formats. Computed targets, and what carrying another one costs.
