> I can share HDR images via phones

Sure, me too! I can take a HDR P3 gamut picture with my iPhone and share it with all my friends and relatives... that have iPhones.

What I cannot do is take a picture with a $4000 Nikon DSLR and share it in the same way... unless I also buy a Mac so I can encode it in the magic Apple-only format[1] that works... for Mac and IOS users. I have a Windows PC. Linux users are similarly out in the cold.

This situation so incredibly bad that I can pop the SD card of my camera into an reader plugged into my iPhone, process the RAW image on the iPhone with the Lightroom iPhone app in full, glorious HDR... and then be unable to export the HDR image onto the same device for viewing because oh-my-fucking-god-why!?

[1] They claim it is a standards-compliant HEIF file. No, it isn't. That's a filthy lie. My camera produces a HDR HEIF file natively, in-body. Everything opens it just fine, except all Apple ecosystem devices. I suspect the only way to get Apple to budge is to sue them for false advertising. But... sigh... they'll just change their marketing to remove "HEIF" and move on.

Not that I disagree, but HEIF is a container format. What is inside that container is essential. HEIC in HEIF, AVIF in HEIF, etc.

    Sure, but Apple doesn't fully support HEIC either.

    They support only a very specific subset of it, in a particular combination.

    Some Apple apps can open third-party HEIC-in-HEIF files, and even display the image correctly, but if you try anything more "complex", it'll start failing. Simply forwarding the image to someone else will result in thumbnails looking weirdly corrupted, brightness shifting, etc...

    I've even seen outright crashes, hangs, visible memory corruption, etc...

    I bet there's at least one exploitable security vulnerability in this code!
