Lookup Tables
 
 
 

A LUT is an ASCII file (Lustre supports the .lut file extension for 1D LUTs and the .3dl file extension for 3D LUTs) that describes specific pixel values used for image data conversion both on input and output. A Print LUT is obtained from your film lab and is updated on a regular basis. If running the Windows version of Lustre, save print LUTs in the C:\Program Files\Autodesk\Lustre 2009.1\lut folder. If running the Linux version of Lustre, save print LUTs in the /usr/Autodesk/lustre_2009.1/lut directory. Lustre provides industry-standard 3D LUTs which are located in C:\Program Files\Autodesk\Lustre Color 2008 SP3\3D LUTs in the Windows version and/usr/discreet/Lustre_Color in the Linux version.

NoteIf you wish to import LUTs into Lustre, you need to copy them to the lut folder.

A monitor calibration LUT is applied to the monitor only and affects the display of images, not the image data itself. It is generated from one measure of gamma (white, grey, and black) or a series of progressive measures for each colour channel. The number of steps in the series is defined in the init.config file. See the Autodesk Lustre Software Installation Guide.
