As I begin to fill up my google photo quota with 65+MB spherical panoramas I am looking for a way to export the originals in a smaller file size. If I make the file dimensions smaller and export from Photoshop the metadata is stripped. Prior to getting an M1 mac there was a program called Spatial Media Medatada Injector but it only works with Intel macs. Anyone know of a means by which I can save out a small version of a 360 pano and inject metadata to allow Google Photos and others to see the image as a 360 on an M1 Mac?
