How to change a MakerNotes?

[ddyner]

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:

Code Select Expand


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


In reply he received the following message:

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.
