it looks like you identified the not-applied lens correction I mentioned here with another camera.
You can easily confirm this via working around the lightroom plugin.
Select the ARW Raw Photo in Lightroom
Right Click the Photo and select “show in Explorer” (I don’t have a windows machine, so perhaps someone can confirm this) to show where the file is stored
open Photo AI from Windows Start Menu (not via Lightroom Plugin!) and load the identified file (I think you can drag and drop it on PAI also)
check PAI Preferences to make sure Lens correction is enabled (which is default on)
*Process the raw file
click on “save Image” and make sure to select “Location = original folder” and “Format=Preserve Input Format”. In the queue you should see a resulting filename as the original filename with a suffix and dng extension. Click Save.
head back to lightroom
select the lightroom folder where the original photo is located. You can do this via right click and something like “goto folder in library”
right click folder and select “sync folder”
keep "import new fotos selected and import
check the imported dng file for the bending you’ve mentioned. I’d bet it is gone.
It would be great if you could verify this for me.
If my Instructions are way to detailed for your knowledge, I apologise.
If my assumtion is right, your problem is the missing lens correction in the PAI lightroom workflow which is especially problematic for lenses with high distortion on cameras which include lens correction information in the RAW files. Sony RX100 seems to be a perfect example, since the need of digital distortion correction is part of the compromise to have such a tiny little camera which such a great potential.
I updated to Photo AI V1.3.6 and figured out that the preview in PAI has got no changes in colour. The change occurrs when pressing the button “save to Adobe Lightroom Classic Plug-in”.
I exported from LR the wrong coloured dng-file into a jpg-file. The colour-bug is persistend so most likely it is not an issue of LR.
