Have you started using Instagram yet? It's a great way to share photos with your friends — and with us! In a nutshell, Instagram is a free photo-sharing application. You take photos with your iPhone or Android, apply a vintage filter, and then share your snapshots on the service and, if you choose, through other sites, including Facebook, Twitter, and Flickr. This gorgeous shot is from marinacas's Instagram stream. She shared it with us by tagging it #CasaSnap.
