There you go, HDR photos that display correctly everywhere. Bunch more information on this here https://gregbenzphotography.com/hdr-images/jpg-hdr-gain-maps...
It's what Pixel now captures by default as well.
I can’t use this technique to publish my photos to them.
I can use an Apple format to send HDR images to my friends and relatives with Apple devices.
I can use some other Adobe or Google formats to send pictures to my friends with Android (=Google) phones.
Etc…
We don’t have any new widely adopted open standards any more in today’s FAANG era of mutually antagonistic fiefdoms.
At best one of them muscles out the competing formats and that becomes a defacto standard.
For everything else we’re stuck with pre-FAANG standards established at a time when companies were smaller, didn’t “own” the whole stack top to bottom, and were forced to cooperate.
Google owns that hardware (Pixel), OS (Android), browser (Chrome), protocol (HTTP3, Brotli), codec (VP9, WEBM), and television itself (YouTube).
There’s an identical stack for Apple.
Why do you imagine it’ll ever be possible for Google user to send a full fidelity photo to an Apple user?
They live on opposite sides of a new iron curtain.
They’re not even permitted to text each other properly!
It's possible today. Apple may just not give you the ability to actually view the image though.
Switch your iPhone to use "high compatibility" or something like that and it'll spit out jpegs with hdr gainmaps that chrome and Android understand as well now. It's not the Adobe spec, but given Apple is now publicly talking about gainmaps ( https://developer.apple.com/documentation/appkit/images_and_... ) and the Adobe spec is a superset of capabilities with a patent-free license and an ISO draft proposal it doesn't seem unimaginable that Apple will move it.
But if Apple won't ever support it, that doesn't mean iPhones can't view it. You already can today with the latest version of Lightroom. And of course Chrome on MacOS already lets you view them. Apple's iOS browser monopoly is hurting you here, but that's very obviously an exclusively Apple created problem
I’m sorry, but a system to decide old nonsensical formats should not require a license.
Also… the gain map is subsampled 1:2. Surely this will cause annoying artifacts at sharp edges where one side is much brighter.
The one that's likely to go to an ISO standard is the Adobe spec here: https://helpx.adobe.com/camera-raw/using/gain-map.html (which is the same as Google's "UltraHDR")
And that has a blanket public grant for usage.
> Also… the gain map is subsampled 1:2.
Subsampling is optional, you can do 1:1 if you want.
“Note for Safari / iPhone users: The top image on this page (the building with the before/after slider) uses a workaround which shows an HDR video as if it were a photo. This will let you get a sense of the HDR benefit, but you will fail the tests below as Safari / WebKit (which means all iPhone/iPad browsers) only supports HDR video and not HDR photos at this time.” :-(
