new tag value is not updated

[jeffbuzz]

I am trying to update the Artist tag value on a file.  When I execute the command, exiftool shows the file was updated.  But if I then check the new file, it still contains the old value.

The file is not read-only and I have admin rights on the folder.

I am deleting the "2018-01-19_1708__DSF0377.RAF_original" file before each new attempt.

Any suggestions as to why the tag value is not being changed?

If ExifTool says the file was updated, then it was.

This is FAQ 3

Using the FAQ #3 command as suggested, my guess is that you will find a second Artist tag, most likely in IFD1:Artist.

Because this is not the main location for this tag, you will have to be specific when writing it.
exiftool -IFD1:Artist="New Name" /path/to/files/

Or you could delete it, leaving only the main Artist tag
exiftool -IFD1:Artist= /path/to/files/

@StarGeek:  I tried this myself but IFD0:Artist takes precedence when reading (from my sample file anyway).  If you have a sample where IFD1:Artist takes precedence, send it to me.

Good to know.  I was just making assumptions as the usual problem in these cases is the wrong IFD.

I just tried it with a random Fujifilm RAF file and IFD1 took precedence

[Phil Harvey]

Ah, thanks.  The RAF IFD priorities are different.  I'll think about changing this.
