IMPORTANT — 3D LUT LIMITATIONS
A 3D LUT records global colour transformations. It cannot record image-specific or spatial effects such as vignettes, film grain, masks, local adjustments or processing that depends on image position or content. Complete Look LUT export includes applicable global colour and tonal transformations only. It cannot guarantee an identical reproduction of every effect visible in the edited photograph.

Toning maps greys onto a colour ramp from shadows to highlights.
