Have a few thousand tiff photos I’ve scanned in over the past few years into Lightroom Classic. For reasons I won’t go into here since not relevant to the question, I’d like to change the year for all photos to be 45 years earlier than what they currently are but want the month day hour and seconds to all stay as they are.
Lightroom has an ExifTool plugin but the docs don’t have an example for just shifting only the year back by a certain number.
Something maybe like,
exiftool "-AllDates-=45:0:0:0:0”, but with only changing year.
