If you like old film presets then consider purchasing DxO’s FilmPack 7. It integrates into PhotoLab and also comes with a standalone interface for use with other software. It has over 100 film emulations as well as a number of other features and most importantly among them are the four fine focus sliders. It also includes the Time Machine feature which gives you film emulations of images from the beginning of photography to modern times.
You can find LUT packages in the Internet.
Some of the packages are free, others are not.
If one wants to use imported LUTs, it’s probably a good idea to put them all in one place. PhotoLab is not too good at organising larger numbers of LUTs and DCP profiles.
