OOPS, I just noticed that photos shot in RAW on my 13 Pro on 15.4b2 are not recognized by my photo editing program (CaptureOne 22). When I try to import them, CaptureOne says there are no photos in the folder.
When I was on 15.3, CaptureOne recognized and could import my RAW photos. In fact, I tried it and CaptureOne still recognizes RAW photos from 15.3. Just not from 15.4b2. I can't speak for 15.4b1 since I didn't shoot anything whle I was on 15.4b1.
Does anyone know if Apple changed something in the DNG format for the 15.4 betas? My Windows 10 PC recognizes them and can display them OK. Just not CaptureOne.
If I can't get to the bottom of this, I'll have to revert to 15.3 for now. In the mean time I'll report it to Apple and see what they say (if anything).
