I transfer my ARW raw files from my Sony Alpha 7iii to my iPhone 11 Pro (iOS 13) using the Apple SD card reader and can successfully see the full quality RAW files on my phone (verified by plugging my phone into my laptop).
I also have Google Photos on my phone set up to upload original files, but when I view them on photos.google.com I can see they've shrunk to a quarter of the size (~6MB) and if you download them, you'll get a file like DSC123.ARW.jpg.
Does anyone know how I can ensure a real ARW file gets stored in Google Photos which I can later download in full quality?
PS: Sorry if this is not the correct stack exchange site to post on, but I thought the combined knowledge of Google Photos/RAW files/iOS is probably pretty good with this user-base.
