How to strip (or add time) to ALL (!) timestamps in EXIF JPG header?

Post by bensto »

Assume I have a couple of *.jpg pictures with a big EXIF header each.

This EXIF headers contains (beside other meta information) some timestamp fields:

date/time
date/time original
date/time digitalized
.....?

How excatly can I (with ImageMagick)
a) strip off all (only) timestamp header fields?
b) add (or subtract) 9 month 4 days and 3 hours and 12 minutes to all timestamp fields?

Thank you
Ben

I think the recommendation is to use the EXIF tool as Imagemagick is not designed to edit EXIF data.
