Thanks for your reponse. I'm using version 4.4 (then it has 3.3 after that). I'm just trying to embed IPC information straight from the RAW image from the CF. I don't really want those large files on my computer, and the editor I'll be dealing with would prefer RAW images with caption information. As for the filename extension I'm not sure. I hope I've provided enough info. here. I can take the pictures, but it's the computer stuff where I'm clueless!
I added support for Sony RAW files (ARW, SRF, and SR2) in version 4.5 but I only enabled the embedding of IPTC data into ARW and SRF files because they were the only files I was able to get feedback about whether embedding IPTC/XMP data into the files caused problems for other software.
It is easy enough to enable embedding on SR2 files, but only if I can get verification that it doesn't cause problems with other software.
Version 4.4.3.3 does not have support for Sony RAW files. Depending on when you purchased Photo Mechanic you may be entitled to a free upgrade to version 4.5 (version 4.5.1.1 is the current version).
