LUTs: A Primer
A “LUT”, or “lookup table”, is an array of preselected values
used in movie color-correction to map colors from the
original input footage to the desired colors in the nal
output. Color correction is performed by looking up input
colors and assigning them new RGB values based on the
data in the table.
A lookup table that treats each of the red, green, and blue
channels separately is a“1D LUT”, which cannot be used to
correct saturation or hue. Such corrections require a “3D
LUT”, in which each combined RGB value maps to a single
combined value in the table.

Using LUTs with N-Log
Designed to take full advantage of sensor dynamic range,
Nikon’s unique “N-Log” logarithmic gamma curve oers
excellent balance between highlights and shadows and is
optimized for 10-bit movie recording. Information on lm-
ing N-Log footage can be found in Technical Guide (N‑Log
Recording Edition) handbooks available from the Nikon
Download Center.

Designed specically for the purpose, Nikon’s N-Log 3D
LUT greatly makes color grading N-Log footage a snap. Al-
though the N-Log gamma curve captures a wide range of
tones, the raw footage will seem to lack contrast and must
be color graded for display on Rec. 709 monitors.

LUTs: A Primer
To color grade N-Log footage using the N-Log 3D LUT, you
will need third-party movie editing software. This guide
shows how to apply the N-Log 3D LUT using Blackmagic
Design’s DaVinci Resolve 15.
Compatible Applications
In addition to DaVinci Resolve, the following applications can
be used with the N‑Log 3D LUT:
• Adobe: Premiere Pro
• Apple: Final Cut Pro X
Note that Nikon neither endorses this software nor guaran‑
tees its operation.
Contact the publishers for information on using these appli‑
cations.
