As well as tagging photos by category and / or keyword I also add captions to provide extra detail.However, the caption for any photo taken on my daughters Samsung Camera shows as “SAMSUNG DIGITAL CAMERA” regardless of what has been typed into the caption box when I save Metadata to file.
It would help to know which solution does not always work.
- The preference setting should prevent to get the Samsung caption at import time. I can imagine a problem if you 'update thumbnail' afterward, which would read again the caption in the file and update the catalog. Otherwise, when adding a new caption, take care of ticking the option to replace the possible old caption.
- The way to force delete captions in the IPTC field should work in all cases.
