Title: How to change a MakerNotes?
Post by: ddyner on November 26, 2012, 03:09:05 PM
Hi, All.

I want to change the property FirmwareDate in the block Makernotes.
My pictures are made camera Casio.
I tried to execute the following command:

exiftool.exe -makernotes:FirmwareDate=%mydate% PictureName.jpg


In reply he received the following message:
Quote
Error: [minor] MakerNotes offsets may be incorrect (fix or ignore?) - PictureName.jpg


How to do it?

You need to use either -m to ignore this problem, or -F to try to fix it.  If exiftool guessed correctly at the actual makernote offsets, then -F is the one to use.  Try both first to see if any of the makernote entries are corrupted one way or the other.

BTW, this is FAQ number 15 (https://exiftool.org/faq.html#Q15).
