Color Grading with LUTs

"Color LUT" stands for Color Lookup Table. Color LUTs are lists that instruct Gemstone or related programs to map specific RGB values to other specific color values. LUTs can be imported to use as filters in ACDSee. LUTs can also be created in the Editor for use in the Develop Tools pane. Apply a Color LUT in the same way as using any other effect in the Develop Tools pane. Color LUT supported file types are .3DL and .CUBE.

To apply a Color LUT to an image:

  1. In the Develop Tools pane, select the Tune tab.
  2. In the Color LUTs group, do one of the following:
    • Select a LUT from the drop-down menu. The LUT is immediately applied.
    • Click the Import LUTs button. In the Open dialog, browse to the location of the LUT files, and click Open.

If an imported LUT file's location has changed, reload it using the Color LUTs panel.

To remove Color LUTs:

  1. In the Color LUTs group, click the Remove LUTs button.
  2. In the Remove LUTs dialog, enable/disable the checkboxes next to the LUTs to be deleted.
  3. Click Remove LUTs.

To refresh the list of Color LUTs:

Refresh the list of available LUTs to reveal moved or deleted files.

In the Color LUTs group, click the Refresh List button.

Color LUTs created in the Editor using adjustment layers will automatically become available in the Color LUTs group in the Develop Tools pane.
