SUMMARY As a user, I would like to be able to use *.cube 3D LUT files to modify pictures. BACKGROUND Currently, it is possible to import custom *.png 3D LUT files but it is impossible to import *.cube files which are a quite popular format. It would be nice to have this possibility. The codec must be implemented. There is the topic where I asked about it: http://digikam.1695700.n4.nabble.com/Lut3D-in-digiKam-td4695429.html ACCEPTANCE CRITERIA There is a possibility to import *.cube 3D LUT file and apply it to pictures using 3D LUT option in the editor.
digiKam Image Editor GmicQt tool has powerful LUT3D filters which allows to use external lut files. https://i.imgur.com/sFjMXIq.png Gilles Caulier
