If you've taken a photo with your smartphone, there's a good chance you've revealed more about yourself than you intended, thanks to the inclusion of GPS in modern phones. Sean and Andy take a look at how photos are "geotagged" with your location, show how to get the information, and talk about how you can turn it off on your phone, if you want.

Metadata, pertinent bits of info that are recorded by your camera when you press the shutter button, can be invaluable to the budding or seasoned photographer. Exifer lets you easily restore EXIF data from an original image and even add tags and other information that will then be embedded into the EXIF. Data like shutter speed and aperture, date, resolution, focal length and a ton of other useful tidbits are there, along with your own categorization tags for easy indexing.

Andy and Sean show how the global positioning system helps you navigate using a melon and tomatoes.
