What this LUT does

Measured from the file itself: it softens contrast (about 28% flatter through the midtones); pulls saturation down around 36%; takes blacks to zero. 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.

Highlight clippingyes — at least one probe pins a channel at 100%

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.
