Instagram is a free iPhone app that allows you to become a photographer in a few clicks. Snap photos of anything, anywhere, at any time and instantly apply filters that take you from random person to Ansel Adams’ protégé. This digital photography is now crossing into the physical word with sites like blurb.com providing hardcopy books of your Instagram photos. We thought this was a great idea for deployments. You can preserve memories on the homefront with your iPhone and gift them to your loved one in a physical book.
