HEIC Photos and Creation Date (Aufnahmedatum)

With my available tools (Canon Digital Professional, File rename Pro, File Muli Tool X etc.)

I was unable to add the creation date to fotos from iPhone (HEIC-Format, i.e., IMG_1234.HEIC) that were sent to me.

After processing they show only the date, when the files were sent to me (Erstellungsdatum ist nicht Aufnahmedatum!).

So I have first to import these HEICs into my Apple Foto Mediathek and export these as JPEGs. Then, the true creation date of the fotos is recognised and can be added to the IMG_1234.JPEGs with all my tools.

Rather uncomfortable for 21th century IT standards!
