Exif Jpeg header manipulation tool
Excellent, multi-platform freeware that can extract and manipulate the EXIF meta-data in JPEG files. It understands IPTC & XMP data as well as EXIF camera data. It can also be used to rename files according to the meta-data.
I use it to batch rename camera images according to their date/time & camera model.
GeoSetter for Windows
Sets Geo data and other meta-data. Uses ExifTool, Google Maps, supports RAW, sync with track files or budy images, make use of locr.com.
Portable, no need for installation. Batch files provided to reg/unreg the shell extensions.
Picassa IPTC data issues
I use this: http://libiptcdata.sourceforge.net/ on Linux.
After some further digging I have discovered the source of the
problem. It turns out that if the "Character Set" (1:90) or
"Version" (1:0) datasets are present inside the IPTC metadata, Picasa
will skip over all the metadata entirely. That's somewhat
unfortunate, but at least I know how to fix it now. Google
developers, if you are reading this, please consider changing this
behavior.
I have also observed that if the IPTC headers are buried deeper in the
image, beyond the "Start of Frame" JPEG marker, Picasa will not find
them. I consider that a bug as well, but it can be worked around.
