Re: [Nuke-users] Writing IPTC photometadata
Andrew, Thanks for the help. After a lot of fruitless research trying to make PNG files display metadata in Photoshop (target app by client request), I have moved to TIFF. With some more work today, I now have a Python afterRender function in Nuke that adds the metadata fields to the rendered images - which *do* show up in Photoshop! I'm calling exiftool in my python function to do the work of adding the metadata tags, referencing a text file that holds all of the arguments for the exiftool command. Through the process of elimination, I discovered which xmp tags that Photoshop uses in their file info display. They are a hodgepodge from the xmp-photoshop, xmp-dc and xmp-itpsCore groups. ...So, to make a long story a little bit shorter, we will be telling our clients that, if they *really* want the metadata visible in PS, they'll need to move away from PNG file deliverables to TIFFs. I spent *way* too many hours figuring this out (mostly beating my head on a wall of PNGs), but I suppose I learned a few things in the process! ;^) Rich Sent from my iPod On Apr 1, 2014, at 3:44 PM, Andrew Mumford a_mumf...@mac.com wrote: What’s your target app - PS or Bridge or non-adobe ?

Re: [Nuke-users] Writing IPTC photometadata
And, then there’s this… http://forums.adobe.com/message/5289378 Although the discussion thread is from 2009, I had the same exact problem - Photoshop deleted the metadata that I had added to my PNG files via Exiftool. Apparently, PS will remove any existing XMP data in a PNG - when the file is modified in any way! (8^P Rich On Mar 31, 2014, at 9:31 PM, Richard Bobo richb...@mac.com wrote: Thanks, Andrew.
