I have turned on the Prowraw option in my camera Settings.However when I take 2 photos 1 with the raw option switched on in my camera app and the other with it switched of both photos are in JPEG Format with similar file sizes.What is the issue here?

Thanks very much for your reply.I have indeed been testing this new Pro Raw option.I have recently upgraded my phone from I phone 6 to 12 Pro.A massive jump which I waited quite a while to do in anticipation of the many new developments.I must say I am generally well pleased with my new phone and the image quality in all formats are excellent.I am however very surprised and disappointed at the awkward and cumbersome file handling system for these new Raw Files.Yes I have successfully used Air Drop,Mail, and Image Capture.However to export a Raw photo from the Photos app on my Mac just onto my Desktop is no where nearly as simple as I would have expected it to be.Surely this should have been as simple as dragging the photo from one to the other.As you will know when I do simply drag a Raw photo it becomes a JPEG.

As an amateur photographer I am very aware of the push to improve and increase the use of smartphones in place of standalone cameras and thus I was very excited to have the option to create Raw photos on my phone.Sadly until the file handling system becomes much more simply managed it's not an option I will be considering in great seriousness.

It's also worth quickly mentioning that the process to view the Meatadata of a photo on the phone is also extremely cumbersome and awkward.Again this is a facility any reasonably experienced photographer would want to have but unfortunately is very messy and prohibitive.Another blockage preventing the move to serious Phone Photography.

Hope Apple may become more aware of these issues and work to improve them in future developments.
