Most smartphones, tablets, and digital cameras add location information to photos, called geotags, by default. Geotags identify the location where the photo was taken which means they would reveal your home address or other locations you frequent with your family. It’s very Important to check this setting on your digital camera devices and make sure that it is turned off.
This Geotag dangers video talks
about geotags, but the instructions for turning off location info on iphones is outdated. The correct method is Settings -> Privacy -> Location Services -> Camera switch to Off.
The Digital Zen blog also has a post with useful information about geotags.
