@simonw FYI, osxphotos includes a built in ExifTool class that uses exiftool to read and write exif data. It's not exposed yet in the docs because I really only use it right now in the osphotos command line interface to write tags when exporting. In v0.28.16 (just pushed) I added an ExifTool.as_dict() method which will give you a dict with all the exif tags in a file. For example:

python import osxphotos photos = osxphotos.PhotosDB().photos() exiftool = osxphotos.exiftool.ExifTool(photos[0].path) exifdata = exiftool.as_dict() tags = exifdata["IPTC:Keywords"]

Not as elegant perhaps as a python only implementation because ExifTool has to make subprocess calls to an external tool but exiftool is by far the best tool available for reading and writing EXIF data and it does support HEIC.

As for implementation, ExifTool uses a singleton pattern so the first time you instantiate it, it spawns an IPC to exiftool but then keeps it open and uses the same process for any subsequent calls (even on different files).
