On Debian and Ubuntu, deploying ExifTool is a matter of running the apt-get install libimage-exiftool-perlĬommand as root. Because the utility is available in the software repositories of many mainstream Linux distributions, it can be easily installed using your distro's package manager. The first step is obviously to install ExifTool on your system. Even if you need to modify a handful of photos, doing so with ExifTool can be more efficient than resorting to your preferred photo management application. If you need to process hundreds, or even thousands, of photos on a regular basis, using ExifTool can save you a lot of time and effort. As is often the case, however, even the most powerful graphical applications can't compete with command-line tools in terms of speed and efficiency. Many photo management applications like digiKam and Darktable make it possible to view and edit metadata. Inside almost every digital photo hides a wealth of useful metadata. In this article, I provide a gentle introduction to ExifTool's capabilities and show how to put this excellent tool to practical use.

Despite its comprehensive documentation, however, coming to grips with ExifTool can sometimes be a daunting proposition.

Indeed, ExifTool can handle practically every metadata-related task you throw at it: from adding and removing tags to performing advanced actions based on specific values obtained from metadata. ExifTool has the well-deserved reputation of being a flexible and infinitely powerful utility for working with photographic metadata.
