Nikon today updated their LUT files for the Z system cameras (Z6, Z6 II, Z6 III, Z7, Z7 II, Z8, Z9, and Zf), incorporating color science from Nikon's RED subsidiary to create cinematic looks that are similar to what the RED cameras provide. Four new LUTs are available: Achromic (monochrome), Film Bias, Film Bias Bleach Bypass, and Film Bias Offset. (Note that this is just four of the 32 Creative LUTs that RED has produced for their cameras.) The Nikon-originated technical Rec.709 LUT is updated and also available.
The new LUTs are available from www.nikonusa.com/content/red-luts.
