This year, the use of Ultra HDR began to be followed by most Android device manufacturers. After Samsung offered it on the Galaxy S24 Ultra and Google introduced it on the Pixel 8 and Pixel 9, other manufacturers like Nothing, OnePlus and many others followed suit. The problem is that when the image is edited with Google Photos, the HDR format will disappear and the image will become SDR. This problem has now been fixed.
In the latest Google Photos update, Ultra HDR image edits will no longer copy the SDR version. Each edit will keep the proper HDR data and the image will still look beautiful. To know which images support Ultra HDR, the display on your device's screen will make the image with high exposure to light appear brighter while other parts are not.
Google uses AI to predict new HDR data on the edited image then recombines it with the original data. Images edited with AI features such as Magic Eraser and so on can also retain the HDR effect. For now only Google Pixel 8 and above users can take advantage of it through Google Photos.
