easyHDR3 costs about $30 and will do exactly what you want with the PhotoLab exports, in a very naturalistic way, very quickly and without much fuss or muss. I believe there’s a free demo. I compared many tools, including Photoshop, Affinity Photo, Aurora HDR and Nik HDR to discover that easyHDR does the best job with deghosting.
There’s an example full resolution photo with windmills on this old post of mine.
Only easyHDR got this really right.
I’d rather DxO continued to focus on their main business of providing a high quality RAW development tool with good colour tools. HDR and panorama can easily be created in other tools from masters made in PhotoLab. I’m not sure about focus stacking as I haven’t been doing it. There’s probably some very nice dedicated tools for that kind of work. It seems to me the first step to effective photostacking is the same as with HDR and panorama: high quality finished masters to merge.
