    How can any device that supports JPG support this Ultra HDR format if it is not exactly to JPG specifications? They mention they embed more data into the file than just a typical JPG so how can software that previous supported JPG know what to do with it?

      It sounds like it’s backwards compatible so places that don’t support the new format will simply get an SDR version of the photo and I’m sure Google will try to get everyone to support this new type of jpg.

        It’s a jpeg

        Then encoded in the metadata is a map of brightness.

        If your website/app/phone doesn’t support it, the metadata just sits there with info about the lens, shutter speed etc.

        If it does support it, the JPEG is automatically processed with the metadata to increase brightness in the original jpeg.

        Ah, that makes more sense. You just get the non-HDR JPG. 👍

    By android 14 they mean pixel 8. No love for the P6. So far the only “feature” I’ve found is that persistent notifications are no longer persistent.

    Is this not backwards compatible with the 7 or 6, or is this another feature drop down the road?

      Below, I’ve embedded some graphics created by display analyst Dylan Raga that illustrate how Ultra HDR works. Using version 9.1.098 of the Google Camera app extracted from a Pixel 8, I took various Ultra HDR photos in a nearby park. These photos were captured on a Pixel 6 Pro, which surprisingly supports saving photos in Ultra HDR just by sideloading the latest version of Google Camera.

      So maybe. or maybe just pro devices. not sure

        I like the sound of the backwards compatible features but they shouldn’t limit this to only the pro models. That’s unnecessary given the previous chips were identical unlike this new batch

          I know you’re just speculating, but I’m just saying my thoughts in general if this went through.
