Google Photos has introduced the Ultra HDR feature, replacing the previous HDR effect, allowing users to enhance the brightness and vibrancy of their photos. The rollout has begun, with select users already experiencing it, and it is part of version 7.24.0.747539053 found in the “Adjust” tab. When applied, images will have an “Ultra HDR” tag in the metadata, and the Ultra HDR version may take up less storage space than the original image due to a compact gain map. Each Ultra HDR file also includes a standard dynamic range (SDR) version for compatibility with non-HDR displays.
