Hi Svetlana, met a slight snag. It doesn’t always work!
I think the issue is 'the Following Presets will be applied to NEW images discovered by DxO.
The trick works on images it’s never met before, but even if one image in a folder has been opened in DxO all the rest default to ‘Preserve Aspect Ratio’. How do i make it forget? I guess it’s a RESET somewhere, but I might accidentally reset something I want to keep!
Or delete the Database, then all images are seen as new and all images are getting the new default preset. @John-M made a small delete script which works fine.
One heads up, the default applied preset can override some made changes you did before depends on how the preset is build. ( The dopfile is renewed when opening the image and the new preset is applied.)
you can test the behavior by applying the new preset on one image manualy.
If you don’t want to change other settings on done image’s, Pieloe’s methode is the best way to update this crop-behaviour…
