Date change when photo was taken before 1970
Posted: Sun Jun 08, 2025 7:35 am
I have digitalised negatives from older photo's. This includes photo's from my parents and grandparents and older familymembers. The original photo's were taken a long time ago. (Long) before 1970.

"For dates, use Metadata>Change timestamp screen...
You can adjust the 3 Exif dates as you wish, but the "File" dates MUST stay later than 1970 01 01 . (This date equals to 0 in operating systems)"
So, that brings me to the questions:
-How to add or adjust the time stamp, and/or add the date the original photo was taken, when this is before 1970-01-01?
-And why equals 1970-01-01 to 0 in operating systems?
(NB people can also be born before 1970-01-01, and it's possible in most systems to add the date of birth of any date).
