The IPTC property names are a little opaque, which is partly why I wanted a script, as I'm highly unlikely to remember that the title is the ObjectName property. Firstly, we used ExifTool to find the current values of the three properties I cared about. There are a few interesting things that I'd like to point out. # set to defaults if we got a blank result
Read -e -p "Description : " NEW_DESCRIPTION IMAGE_KEYWORDS=$(exiftool -s -s -s -iptc:Keywords "$1") IMAGE_DESCRIPTION=$(exiftool -s3 -iptc:Caption-Abstract "$1")
It's a lovely tool with many options, so I wrote a script to make it easy, and while I was there, I used read to prompt me for the info to set. I recently needed to change the title and caption of some photos, so I turned to ExifTool, as it's the Swiss Army knife of image metadata.
