    Once a picture is taken and compressed into a jpeg (or whatever) why is there a need for any extra support beyond “sending an image”?

      Ultra HDR is a new image format available with Android 14 on supported devices & camera. Basically it’s a JPEG image but some additional data added to it when captured on supported devices. With ultra HDR, images can have darker shadows and brighter highlights.

      I thought the same thing at first, but it sounds like it is just that you can now view the “Ultra HDR”-ness within the app.

      Also,

      Google Messages doesn’t strip the gain map metadata from images

        Yeah I guess it probably strips unknown data segments from the file for security and privacy, and it would have a whitelist of segment types it will keep

        And of course the ability to display them with ultra HDR

      Well, it does spell out the difference of Ultra HDR. However, you asked “need?” There is absolutely no need (in my opinion) of better pictures, but I also rarely take or view them so I might not be the best judge.

      Obviously it’s not exactly a 1:1 comparison, but think of the image having HDR metadata like an HDR YouTube video. Even though it’s compressed, it could still contain HDR attributes like 10-bit color or a certain screen brightness when viewing the specific images.
