Phil Harvey has posted ExifTool v12.42, the first production release since v12.30 on Aug. 18, 2021. The small download is available three formats, including a Windows executable and Macintosh OS X package.

Changes since the last non-production release include:

- Added support for reading maker notes from Panasonic DC-GH6 videos

  • Added conversion for Samsung MCCData
  • Added a new Nikon LensID
  • Added a few new Canon LensType values
  • Added a couple of new Olympus StackedImage values
  • Added a few new values for some Nikon Settings tags
  • Added a "lang:" element to the -json output for alternate language tags when -D, -H or -t is used
  • Update DNG writer to not issue an error when writing DNG 1.6 files
  • Decode information from DJI "ae_dbg_info" maker notes
  • Decode Olympus AISubjectTrackingMode
  • Changed ExifTool FileSize print conversion to use kB/MB/GB units instead of KiB/MiB/GiB
  • Changed "is not shiftable" warning to appear in -v (instead of just -v3) output
  • Patched to allow PDF Encrypt object to be "null"
  • Fixed bug reading ICC_Profile meta tags

In addition to the production releases, Harvey posts regular updates to ExifTool to handle new cameras and newly-decoded tags. His site includes an encyclopedia of Exif Tag Names in addition to extensive documentation and links to other resources.

We rely on the Perl library to write copyright information into the Exif header of our JPEGs and into DNG files. We also use it to read Exif header information. Our Services page includes a blow-by-blow account of building an OS X contextual menu service using ExifTool and we've added a Services Request form so you can request our help with your own software development.

We've explained how to reset the capture time in your images with ExifTool in Spring Back After The Fact. And we've written about using the tool in Copyrighter Pro to add copyright information to your images, as well. Most recently, we published Using Exiftool as an Image Organizer.

It's really the Swiss Army knife of Exif data.
