    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. 👍
