Hi, I am having a problem subtracting an integer from the value of one of my tags. I have tried -tag-=10 but it still doesn't work. Any help would be greatly appreciated!
It helps if you show your work. What is your exact command and the complete output. Copy/paste all of it and use the Code Button (https://exiftool.org/forum/index.php?topic=4888.msg69111#msg69111).
