Preamble
The L-Log LUT Pack has been developed to support quick and easy normalization of L-Log content across Monitors/Recorders and Editing/VFX applications that do not support the L-Log OFX Plugin. All LUTs have been developed programmatically to ensure the highest level of accuracy possible for a Look-Up Table. These are Technical LUTs can be used as Camera Input LUTs in programs such as DaVinci Resolve, Final Cut Pro and Adobe Premiere, or across Field Monitors/Recorders such as the Atomos Ninja/Shinobi/Shogun series. The L-Log LUT Pack includes standard L-Log as well as L-Log for the SL Typ 601 camera with additional Output LUTs that have Tone Mapping.
The LUT Pack complements the L-Log OFX Plugin which is geared for Applications that support the OpenFX standard and the L-Log Transform which is targeted as an ACES IDT for DaVinci Resolve. For reference, L-Log is correctly exposed at 44% IRE. The graph below also plots the L-Log curve against exposure values.
Installation
The LUTs should be copied to the designated LUT folder hierarchy of your desired Application or Monitoring System. This will vary from one application and Recorder/Monitor to another.
Windows
Depending on the target application, the LUTs may need to be copied to some of the following folders on Windows based systems:
- C:\ProgramData\Blackmagic Design\DaVinci Resolve\Support\LUT\
- C:\Program Files\Adobe\Common\LUTs\Creative
- C:\Program Files\Adobe\Common\LUTs\Technical
MacOS
Depending on the target application, the LUTs may need to be copied to some of the following folders on Mac OS systems:
- /Library/Application Support/Blackmagic Design/DaVinci Resolve/LUT
- /Library/Application Support/Adobe/Common/LUTs/Creative
- /Library/Application Support/Adobe/Common/LUTs/Technical
Linux
Depending on the target application, the LUTs may need to be copied to some of the following folders on Linux systems:
- /home/resolve/LUT
Usage
The LUT Pack consists of 40 LUTs with the following specifics:
- A Technical Transform LUT with output to P3 D65 or Rec.709 Scene
- A Technical Transform LUT with output to P3 D65 or Rec.709 Gamma 2.2
- A Technical Transform LUT with output to P3 D65 or Rec.709 Gamma 2.4
- A Technical Transform LUT with output to P3 D65 or Rec.709 Gamma 2.6
- An Output LUT that converts to P3 D65 or Rec.709 with proper Tone and Gamut mapping
The Technical LUTs provide a base conversion, from which additional color grading and tweaking can be done. On the other hand, when the Tone Mapped Output LUT is selected, no further color grading or tweaking is required as this will map the color and dynamic range to cover the Rec.709 or P3 D65 Color Gamut and brightness level outputs.
All LUTs are included in either a Video Legal range for host applications such as Adobe Premiere and External Recorders/Monitors or covering the full Data range for program such as Final Cut Pro and DaVinci Resolve.
