How to deal with [minor] warnings

[evdalen]

I get the following warnings when I execute the following command: exiftool -r -k "-FileName<CreateDate" -ext jpg -d "%%f.%%e" "-filemodifydate<createdate#" "."

Warning: [minor] Adjusted MakerNotes base by 4150 - ./17 maart F1/IMG_3788.JPG
Warning: [minor] Fixed incorrect URI for xmlns:MicrosoftPhoto - ./_DSC5878.JPG

Does it matter?

Hi evdalen,

The second warning really is a very minor warning and basically tells you the software you used to edit the file used an incorrect name for the specified xmp block. The first one, could be more serious and basically means the software you used to edit the file (you should never get this from a file directly form the camera), has screwed-up the MakerNotes (camera specific metadata) in the file. Most of the time, however, the data is simply moved to a wrong location and exiftool can fix that by moving it to what it thinks is the right position.

I am using Adobe Lightroom 5. Accidently, I saved the metadata back to the JPG files.

How could I fix this?

Lightroom does not complain about it. So, does it really matter?

I am surprised that you think it was an Adobe product that caused these problems.  It really looks like a Nikon product to me.  See this post.  Also, it looks like a Canon image because the MakerNote offset error was fixed automatically.

So I'm guessing you edited a Canon image with Nikon software to do this.

The good news is the ExifTool should have fixed both problems.  Adobe products are largely ignorant of MakerNotes information, so they would never warn about this.
