Exiftool and metadata: preliminary information.Steps to clean up messy image metadata, with page links: This doesn't mean that all the exiftool command examples on this page still work exactly the same as they did when I first posted the article. Although this article was written in 2012, Exiftool and the Exiftool syntax seldom change except to add new tags and new capabilities. Please don't assume that digiKam still writes all the odd tags that it wrote in 2012, although in fact it might.Ī word about Exiftool: Exiftool is a mature and reliable metadata reading and writing application. This page should be interpreted as describing an approach to locating and cleaning up unwanted metadata, whether or not you use digiKam.

If you allow more than one DAM software to handle your image files, you can pretty much count on each one leaving its own cruft behind. However, if your DAM software has made a hopeless mess of your image metadata, you might find useful some of the individual steps I took to get my own image metadata back into acceptable order. Your approach to digital asset management ("DAM") undoubtedly differs from my own. But fixing the bug doesn't automatically fix whatever mess your metadata might have been left before the bug was fixed. As an important aside, this bug was fixed probably since digiKam 3.5 (it was fixed in August 2013) and certainly by digiKam 4.2. Because of a digiKam bug that prevented image keywords and database keywords from keeping in synchronization with one another, my hierarchical keyword information was a mess. I have used digiKam to manage my photographs since around 2010.DAM metadata standards have evolved rapidly ("exploded" might be a better term) and some metadata that was valid even five years ago is now deprecated.My copyright and contact information has changed since I started using DAM software.I have changed my mind several times regarding what metadata I really want in my image files.Over the years I've used several different DAM softwares, each one of which left behind assorted bits of unwanted, misplaced, or out-of-date metadata.Here's how I managed to mess up the metadata in my photographs: Part 2 covers my revised ingestion process.
EXIFTOOL OPTIONS HOW TO
Part 1 (this page) discusses how image metadata can get really messy and how to use Exiftool to clean up the mess. This two-part article on digital asset management was prompted by the realization that the metadata in my collection of digital image files was in a sad state.
