# Applying an Existing Input LUT

An input LUT can be used to convert and gamma correct the logarithmic or linear data. Apply an input LUT to a shot to remap the colour values. Input LUTs are applied on a shot-by-shot basis and can be toggled on and off.

The settings in the Input LUT menu are saved in grade files. This applies to both 1D LUTs and 3D LUTs. When you use a grade from another station that contains an input LUT that does not exist on your station, the input LUT will appear in the Input LUT list, under Extra LUT from Grade. You can apply this LUT to other shots in the timeline.

NoteWhen a LUT is imported into Lustre, it is automatically embedded in the grade file and can therefore be rendered on remote rendering systems without the original LUT file being present.

To apply an existing input LUT:

1. Select a shot in the Storyboard to which you want to apply an input LUT.
2. In the Input LUT menu, select either a 1D input LUT or a 3D input LUT from the Input LUT list and then enable Custom.

   The input LUT is applied to the current shot.

3. To select a LUT originating from another station, expand Extra LUT from Grade in the Input LUT list, and then select the LUT.

To turn off an applied input LUT:

1. Select a shot in the Storyboard with an input LUT.
2. In the Input LUT menu, disable Custom.

   The input LUT is no longer applied to the shot.

3. Click the input LUT in the input LUT list to remove it completely.

   The input LUT is deselected.
