The zip holds the same LUT twice: a 65-point file for editing, and a 33-point file for monitoring on a camera or in an app, or for older apps that won't load the larger one.

Built from Fujifilm's published spec and checked against Fujifilm's own LUT.

With the LUT

Shot on Sony FX30 (S-Log3) and re-encoded into F-Log / F-Gamut to show the conversion.

The LUT converts F-Log with F-Gamut color, as the manufacturer publishes them, into Rec.709 through the ACES 2.0 output (SDR, 100 nits).

Built from: Fujifilm, F-Log Data Sheet.
