I use AtomicView to class my pictures. I allway put keywords with PM.
My choice in PM is : copy EXIF date to IPTC date.
All is fine between PM and AV but formats.
EXIF date read as 06.02.2010
IPTC date read as 20100602 not pleasant ! I wish separators of any sort.
I asked AV about that, they say "PM has saved in this format ".
Thanks
