This evening I started looking through archived DNG files on external hard drives taken on the following Pentax cameras: K-M, K-50, K-01, K-20D, K-5, K-5II, K-3, K-S2, 645D. I noticed when choosing get info on any of the files in Mac OS Big Sur, it says Affinity Publisher is the default application to open the DNG files. This is before and after updating to the latest version of all three Affinity apps. Particularly in respect to Affinity Publisher because it shows as the default app in finder, get info, to open these files. I didn't try opening any of the files yet. Could this be related? And if not, why would Affinity Publisher show in Mac OS Big Sur as the default, not Affinity Photo?
