Title doesn't show up on photoshop

[pauloHess]

Hi

I have 100 images and trying to do a simple thing i.e. embedding the title of the image. So I use:
exiftool -Title="some-title"   <file_name> or (-XML:Title)
for most images the title shows up on both "Photoshop description tab under document title" and "Windows viewer-> property ->details".
for few images, it doesn't show up on photoshop but shows up on Windows veiwer.
When I check with exiftool:
exiftool -a -G <file_name> I can see the title is embedded.
I checked these few images, nothing wrong them. Any idea what goes wrong.

Thanks

My guess is that the files that don't work contain IPTC.  Photoshop may ignore the XMP if the IPTC exists and IPTCDigest has not been updated.  To be thorough, for files that contain IPTC you should also write the title to IPTC:ObjectName and set -Photoshop:IPTCDigest=new to update the digest.

But this is just a guess.  In general, this comes under the heading of FAQ number 3, and the question is better posed in a forum for the other software.
