ExifTool commands

# Move Description tag to Title tag
exiftool '-Description>Title' *

# Move Title tag to Headline Tag
exiftool '-Title>Headline' * 

# Rename from tag, adding number if necessary for uniqueness, 
# without changing file dates.
exiftool '-FileName<${description}%-c.jpeg' '-DateTimeOriginal>FileModifyDate' *

# Workaround for iPhoto ’10’s boneheaded behaviour of being unable to 
# add IPTC tags for keywords and titles to images without recompressing them:
# 1. Export the original format without the tags from iPhoto
# 2. then export JPEG format with IPTC tags
# 3. then use this command to copy the IPTC tags over
# (Caveat: the file names need to be the same, which can be difficult to achieve with
#    iPhoto’s strange way of changing the capitalisation of file name extensions)
