Hi David
I tell you what, It works with Capture One 20 where it has a plug-in specifically linked with Helicon Focus where Capture One automatically fires off the Fuji GFX Raw file and as far as I am aware X-trans Raw files directly into Helicon Focus where you do what you need to do with the focus stacking whereupon it automatically fires the exported stacked focus file back to Capture One 20 as a Tiff. The file looks very clean from what i can see and “worm free”.
