I'm using v2.2.3. It's packaged with ExifTool v 10.6.7 I think, and DCRaw 9.27.1.1. Camera is Canon 5Dmk4.
When processing one image at at time, EXIF copies over. When batch processing, it does not. I do have "Store EXIF data" checked, as well as "Store GPS data". I updated to the new ExifTool v10.86 and it still does not work. Could the ExifTool commands in the batch processing code skip this altogether?
