I have opened windows of photos in Affinity Photo that I want to combine in an HDR image. How can I add these open windows directly to a new HDR merge? When I select a few photos in the desktop Mac Photos with the Affinity Photo plugin extension, Affinity Photos opens with windows for the selected photos open. However, when I select new HDR merge, I can't find the photos already open in Affinity Photo to add to the HDR merge and I can't enter the Mac Photos Library through the HDR merge window's "add" button. My tedious work around has been to export the selected photos from Mac Photos to a separate folder and then add the exported files to a new HDR merge, then after creating a new HDR image in Affinity Photos, import it back into Mac Photos. The whole process uses my time and storage very inefficiently and defeats the whole purpose of the Affinity plugin for Mac Photos, so there must be a better way that I haven't been able to discover. I look forward to your guidance in using the Photos plugin to efficiently create HDR images.
