Nice image, Alex! Beautiful lighting! Fun to see Fenna again!
Back in the summer of 2018 I purchased Luminar 3 and liked it for a lot of things but then in the fall of 2019 discovered DXO Photolab 3 and really prefer that program for most of my editing now. I still do hop into Luminar 3 for some occasional last-minute fine-tuning touchups, especially if there are things which need to be gently erased from an image, as I prefer the way Luminar handles this. Never got around to Luminar 4 and probably at this point won't bother since I am using DXO most of the time now anyway.
