What is HDR Gain Map?
HDR Gain Map is Apple’s officially supported next-generation HDR format.
It keeps the original SDR image intact while adding brightness enhancement data, allowing the same photo to:
* Display correctly on standard screens
* Shine with higher brightness and richer detail on HDR / XDR devices
This app follows the standard HDR Gain Map workflow, producing HDR files that are fully recognized by the system.
