About N-Log 3D LUT

The N-Log 3D LUT is a color grading tool designed specifically for color grading N-Log footage. Nikon’s N-Log logarithmic gamma curve is optimized for 10-bit movie recording and offers excellent balance between highlights and shadows. However, the raw footage may lack contrast, and the 3D LUT can be applied post-production to create pictures that display beautifully on monitors that support Rec. 709.

Using N-Log 3D LUT
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 17.

Installation and Downloading

Before proceeding, you will need to install DaVinci Resolve and download the N-Log 3D LUT. Follow the below steps:
Install DaVinci Resolve from the official website: https://www.blackmagicdesign.com/products/davinciresolve/

1. Download the N-Log 3D LUT from the Nikon Download Center: https://downloadcenter.nikonimglib.com/

Applying the N-Log 3D LUT
Once you have installed DaVinci Resolve and downloaded the N-Log 3D LUT, follow the below steps to apply it:

1. Launch DaVinci Resolve 17 and start a new project. In the Project Manager, click [New Project] and name the new project as desired.
2. Click the Project Settings ( ) icon.
3. Select [Color Management] in the project settings window and click [Open LUT Folder].
4. Create a sub-folder under the LUT folder, name it as desired, and copy the N-Log 3D LUT to the new sub-folder (named Nikon in this example).
5. Click [Update Lists] and then click [Save]. DaVinci Resolve will load the new LUT.
6. Drag N-Log footage from the operating system file navigation window into DaVinci Resolve 17. If the frame rates of the footage and project do not match, a message will be displayed. Click [Change] to update the project frame rate to match the footage.
7. When recording footage to an external HDMI recorder, check that the [Data Levels] option in DaVinci Resolve 17 matches the option selected for [HDMI]> [Output range] in the camera setup menu. Right-click the thumbnail for the footage in the Media Pool, select [Clip Attributes], and check the option selected for [Data Levels]. If the footage was recorded with [Limited range] selected on the camera, choose [Video]; if it was recorded with [Full range] selected, choose [Full].

Note that this guide assumes you are using DaVinci Resolve 17 as your movie editing software.

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 final 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 offers excellent balance between highlights and shadows and is optimized for 10-bit movie recording. Information on film- ing N-Log footage can be found in the Z 9 Reference Guide available from the Nikon Download Center. https://downloadcenter.nikonimglib.com/https://downloadcenter.nikonimglib.com/

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 17.

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
