Hi,

i am using this commandline to update a IPTC field in a tif file:

exiftool "-IPTC:Caption-Abstract=new_test" /tmp/iptcori.tif

Image ExifTool says '1 image files updated' but checking with exiftool -g shows that the record is not updated. After converting the file to a jpg with imagemagick and executing

exiftool "-IPTC:Caption-Abstract=new_test" /tmp/iptcori.jpg

This worked find.

Further investigation shows that if i convert the jpg back to a tiff with imagemagick and reexecuting exiftool everything is fine. So i assume that exiftool has problems updating a photoshop tiff. I did various test of tiff fileformat but no combination worked. I was unable to write Caption-Abstract or City IPTC data to a tif which is saved with Photoshop.

Is this a known problem? I am using version 5.77

regards, David

Hi David,

I just verified that this works with all my test TIFF images.  There must be something specific about your TIFF file that is causing problems.  If you could email it to me at philharvey66 at gmail.com, I'll be able to figure out what is going on.
