Retrieve Image description with Python (not returned in EXIF data via PIL or exifread)

Question

I want to get the description of an .jpg image. It gets shown in the Mac OSx Info (cmd +i) window.

I want to read the "description" (Beschreibung in German) field. Trying this with PIL and exifread lead to no success.

I can get these exif Tags, but they do not include the description or keywords.

I assume these fields are not EXIF data? What do I need to look for in order to get the description?

Answer 1

Thanks to @Mark Serchells answer, I found that the description is no EXIF data but IPTC data (exiftool shows all the fields).

In Python I now can use IPTCInfo3: https://pypi.org/project/IPTCInfo3/ and extract the description via:

info = IPTCInfo('img.jpg')
info['caption/abstract']

Which prints:
