Hey Amazinglyamazing,
I do not use this feature so I apologize if this info is redundant or unhelpful. I checked the user guide. It seems if you export as a JPEG which is a small file size image type it will not include that info unless I am mistaken. That info is not mentioned other than that you can request to be separated if you export as the original file type.
Here is that user guide section. I will also paste the section for export in original format. Export photos, videos, and slideshows from Photos on Mac - Apple Support
"Export photos in their original format
You can export photos in the original file format in which they were imported into your Photos library. A Live Photo is exported as two separate files: a still image file and a video file.
- In the Photos app on your Mac, select the photos you want to export.
- Choose File > Export > Export Unmodified Original.
- If you want to export IPTC information (assigned IPTC metadata and keywords) as a sidecar XMP file, select the Export IPTC as XMP checkbox.
- Click the File Name pop-up menu and choose how to name the exported files (this step is optional).
- You can name your exported files using the titles you’ve given them in Photos, their filenames, or a filename numbered sequentially. If you choose Sequential, you can specify text to appear before each number (for example, Birthday - 1, Birthday - 2, and so on).
- Click the Subfolder Format pop-up menu and choose how to divide the exported files into folders.
- For example, if you export photos from several different days, you can have Photos export each day as a subfolder named after the day. Choose None to export the photos as individual files without subfolders.
- Click Export.
- Choose where to save the exported photo files, then click Export Originals."
I hope this is helpful for you,
