Default LUT Settings

By default, Nuke uses the following LUTs in the following cases:

File Type / Device	Default LUT
monitor. This is used for postage stamps, OpenGL textures, the color chooser display, and all other non-Viewer image displays. Also used by Truelight nodes when conversion to or from monitor color space is required.	sRGB
8-bit-files. This is used when reading or writing image files that contain 8-bit data. Also used by the Merge node’s sRGB switch, and to convert Primatte and Truelight nodes’ inputs into sRGB and their outputs from sRGB. The Cineon LUT is also used to control the input to Truelight.	sRGB
16-bit files. This is used when reading or writing image files that contain 16-bit integer data (not half float).	sRGB
log files. This is used when reading or writing .cin or .dpx files. Also used by Truelight nodes when conversion to or from log color space is required.	Cineon
float files. This is used when reading or writing image files that contain floating-point data.	linear

To Change the Default LUT Settings

Select Edit > Project Settings to open the settings for the script.

Go to the LUT tab.

From the dropdown menus under Default LUT settings, select the LUTs you want to use by default for each file type or device.

The new defaults are now used for any LUT setting where you have not selected a specific LUT. Any controls you have set to a specific LUT (that is, not set to default) continues to use the selected LUT, and only those set to default are affected.
