Log-Lin View LUT
The Log-Lin LUT converts logarithmic data to linear, and vice versa. This can be particularly
useful when used in conjunction with supplied LUT files that expect logarithmic data. It is similar
to the Cineon Log node.
Gamut View LUT
The Gamut LUT converts a source color space to an output color space, with options to deal
with gamma settings, alpha channels, and premultiplication. The Gamut LUT is a frequently
used LUT type to correct the viewer when working with Linear Gamma in the Node editor.
Macro LUTs
Any macro node can also be used as a viewer LUT simply by saving the macro’s .setting file to
the correct Fusion directory.
In DaVinci Resolve, LUTs are saved in the following locations:
 On macOS: Macintosh HD/Users/username/Library/Application Support/Blackmagic
Design/Fusion/LUTs/
 On Windows: C:\Program Files\Blackmagic Design\Fusion\LUTs
 On Linux: home/username/.local/share/DaVinciResolve/Fusion/LUTs
In Fusion Studio, LUTs are saved in the following locations:
 On macOS: Macintosh HD/Users/username/Library/Application Support/Blackmagic
Design/Fusion/LUTs/
 On Windows: C:\Users\username\AppData\Roaming\Blackmagic Design\Fusion\LUTs
 On Linux: home/username/.fusion/BlackmagicDesign/Fusion/LUTs
For this to work, the macro must have one image input and one image output. Any controls
exposed on the macro will be available when the Edit option is selected for the LUT. For more
information about creating macros, see Chapter 57, “Node Groups, Macros, and Fusion
Templates” in the DaVinci Resolve manual or Chapter 6 in the Fusion Studio manual.
LUT Presets
All LUTs available to DaVinci Resolve are also accessible to the Fusion page, which includes
custom LUTs you’ve installed, as well as preset LUTs that come installed with DaVinci Resolve,
such as the highly useful VFX IO category that includes a wide variety of miscellaneous to
Linear and Linear to miscellaneous transforms. All of these LUTs appear by category in the
viewer LUT menu.
Fuse LUTs
Fuses are scriptable plug-ins that are installed with the application or that you create in Fusion.
A fuse named CT_ViewLUTPlugin can be applied as a LUT to a viewer. You can also script fuses
that use graphics hardware shaders embedded into the LUT for real-time processing. Since
fuse LUTs require shader-capable graphics hardware, they cannot be applied in software. For
more information about Fuses, see the Fusion Scripting Guide located on the
Blackmagic Design website.
