Hi Arnaud,
Since the last beta, PTGui includes the 'uniquecameramodel' tag in the
DNG output. I think this fools ACR to treat the image as an actual
camera raw file, overriding/ignoring the metadata, and (as Erik says)
cropping off the edge pixels.
Could you share your project and source images with me so I can
investigate? Please share with
sup...@ptgui.com via wetransfer, google
drive or similar.
Kind regards,
Joost Nieuwenhuijse
