Sorry, but I should be able to get this to work - but I can't. Maybe I need more coffee
I want to concatenate two fields into one...
Destination field - ImageDescription
Source Fields - IPTC.ObjectName and IPTC.Caption-Abstract
exiftool "-ImageDescription<$ObjectName $Caption-Abstract" {file}
I get the error:
Warning: No writable tags set from {file}
0 image files updated
1 image files unchanged
I know I am doing something silly, but I can't see it
Thanks
Do both tags exist? What OS are you using?
The command you gave works in Windows CMD as long as both ObjectName and Caption-Abstract. If one of them doesn't exist, then you should get a warning like
Warning: [minor] Tag 'Caption-Abstract' not defined
If you are not using Windows CMD, then change the double quotes into single quotes.
That was it :-)
MacOS - Changed the double-quotes to single-quotes.
Many thanks
Phil
