This plugin enables exporting in the Gainmap HDR HEIF format from Lightroom Classic.

Starting with LRC 14.0, HDR export is supported, but it doesn’t include Gainmap support, which causes compatibility issues on Android devices. This plugin resolves that problem.

Note: Currently supports Lightroom Classic 14.0 and macOS 15.0 only.

Gainmap code is from PQ_HDR_to_Gain_Map_HDR
