Hack Your Exif Data from the Command Line: Five Fun Uses for Exiftool
It happens every time you press the shutter. Tiny circuits spring into action and furiously record the information from every sensor pixel onto your memory card. But pixel information is not all that is recorded. With every shutter press, your camera records dozens of interesting details about how the photo was taken. These details are tucked away deep inside the labyrinth of code that comprises your photo file. Photo editing softwares, such as Photoshop or Lightroom, can unlock some of this data for viewing later. But they normally only scratch the surface of the available information by displaying only the most commonly used Exif tags.
To mine the deepest depths of your Exif data, you may want to try a utility called Exiftool. This utility is known for its ability to squeeze every last drop of information from your Exif data. Don’t expect a slick, graphical interface, though. Although there are more user friendly softwares which incorporate the Exiftool engine, we’re going to demonstrate Exiftool where it is at its minimalist best – at the command line.
