> It's not an Apple format Create a HDR HEIC file on anything other than an Apple Device. Upload it to an Apple Device. Now use it any way: Forward it, attach it to a message, etc... This won't work. It won't ever work because the "standard" is not what Apple implements. They implement a few very specific subsets that their specific apps produce, and nothing else. Nobody else implements these specific Apple versions of HEIC. Nobody. For example, Adobe Lightroom can only produce a HEIC file on an Apple device. My Nikon camera can produce a HDR HEIC file in-body, but it is useless on an Apple device because it's too dark and if forwarded in an iMessage... too bright! It's a shit-show, comparable to "IPv6 support" which isn't.
