I am trying to understand how to add "Photosphere XMP metadata" to full spherical panoramic images using Imatch. If anyone knows and could share their workflow it would be greatly appreciated.
https://developers.google.com/streetview/spherical-metadata (https://developers.google.com/streetview/spherical-metadata)
I dont't know if ExifTool knows about this proprietary Google namespace yet. And when ExifTool does not know about it jet, none of these tags will be available in IMatch.
I would start by contacting Phil first via the ExifTool forum.
Managed to trace it to the Gpano xmp tags which Imatch has listed. Google calls the group of tags Photosphere XMP which was what was confusing me. I'm good to go!
