I have just installed a RAW photo app on my iPhone.
It produces .dng files but, at the moment, although I can read it in Affinity Photo, Luminar and on1 Photo Raw and can even read it in Photoshop CS3 by converting it to another version of DNG, I still can't read it in DxO PhotoLab.
IS there anything I can do to the EXIF data to convince DxO to play nicely?
