Is it suitable for beginners?
LUT s are not difficult to use, but they are better for intermediate and expert users who will have the time and understanding to bring out the best results. You will also need the profiles support which is only found in the latest Lightroom CC versions.
Presets are really easy to use, even for beginners. Many of these use Graduated Filter effects really effectively. However, these don’t rotate correctly for vertical in Lightroom Classic and CC; this needs a Lightroom fix or duplicated ‘vertical’ presets.
