I have a few thousand photos I need to process. Each photo is embedded with some data (a latin name) in the IPTC metadata field “supplemental categories”. I am trying to simply set the contents of this field to a variable, then insert this variable into another IPTC metadata field “intellectual genre” and then save. I am pretty competent in AppleScript however I do not know the commands to do this. I do have Photoshop CS4, but the scripting guide does not show any info for the “intellectual genre” field. In an ideal solution I would not have to open the file because rendering 50Mb files to edit text doesn’t sound very efficient, but I could always let the script run overnight.
Thank you guys so much!
