I am getting an error when trying to export an image from PL7. It occurs when I have a local adjustment with a brush mask. When I remove the adjustment layer the export works. The error is: “Internal error (Correction failed on the Execute stage)” The export is to a 16 bit TIFF.
DxO will need to reproduce this. I suggest that you open a ticket at support.dxo.com and provide a sample RAW image and its sidecar file(s).
I managed to get it working by copying the settings to another photo, resetting the photo, deleting the .dop file then copying the settings back again. I assume the file was corrupted somewhere.
