Interpret Footage ▸ Color Management now offers "Fujifilm F-Log / F-Gamut", "Fujifilm F-Log2 /
F-Gamut" and "Fujifilm F-Log2 C / F-Gamut C" (X-S20, X-H2S, X-T5, GFX…), implemented from
Fujifilm's GFX ETERNA Technical Guide white paper v1.01 (the F-Log / F-Log2 data sheet
formulas): 10-bit code-value domain, F-Gamut = BT.2020 primaries, F-Gamut C primaries
(0.7347, 0.2653) (0.0263, 0.9737) (0.1173, -0.0224). Round trip and monotonicity tests cover
the new curves with the others; reference values from the white paper's table: 0 % → 95,
18 % → 470 / 400, 90 % → 705 / 570 (F-Log / F-Log2).
