The 17 channels are currently only available in the Curves filter under Enhance > Adjust Lighting > Curves. The Curves adjustment layer only offers RGB curves.
A future version of ElementsXXL will very likely offer all 17 channels in the Curves adjustment layer too.
Paint Shop Pro X6 was the first 64-bit version. There is also a 32-bit version, with which all 32-bit plugins have to be used.
ElementsXXL 5 arbeitet mit Photoshop Elements 11 bis 2018. Für Photoshop Elements 1 bis 10 stellen wir auch ältere Versionen von ElementsXXL zur Verfügung.
Also, Sie können ElementXXL im Prinzip mit jeder existierenden Version von Photoshop Elements verwenden.
In Lightroom go to Edit > Preferences > External Editing. Under Presets please select FocalBlade, then click on the Choose button and select FocalBladeLR.exe in the FocalBlade installation folder under C:\Program Files\The Plugin Site\ This will make sure that Lightroom is able to run FocalBlade.
Photoshop itself includes some HDR Features, but they are not that great. The free nik Collection from Google contains a HDR plugin for example.
Sorry for the delayed reply. I was finally able to reproduce the problem. I will send you a fixed version ASAP.
