Tip of the Day 11/19:Puzzle caches —pictures

Find It Friday is taking a turn for the puzzling the next few weeks. We’ve heard from a lot of cachers that they don’t even try puzzle caches because they just don’t know where to start. We’re here to help, as always! We found a great resource on the Geocaching NSW site and Darren Osborne has agreed to let us share it with you.

There is more to a picture than the picture itself. Some contain ‘hidden’information known as EXIF data. Look at the file’s properties or use a photo editing program to look at the data included with the image to see if there is anything hidden.

Changing various attributes such as brightness,contrast,alpha channel or colour depth may also reveal information.

Try inverting images,or using filters such as ‘Local Equalization’ and ‘Find Edges’ if available. If you don’t have Photoshop,you may find these free software titles useful:

  • Gimp (for Windows,Mac and Linux)
  • Paint.Net (for Windows) along with the BoltBait plugin pack that includes a steganography tool!
  • SplashUp (online tool)
