Preview: to save from .DNG directly in .JPEG
Hi to all.
I have a Macbook Pro with Catalina 10.15.6.
If I open, in Preview, a photo in .DNG and I modify it, when I try to save appears the sentence "The file xxx.DNG does not support the modification" (in Italian language the sentence is: Il file xxx.DNG non supporta la modifica).
I would like to save the file from .DNG in .JPEG but I can only save it in .TIFF.
How can I do to save, in preview, from DNG in JPEG ?
Thanks to all.
