I recently checked my personal google plus account to store and delete some pictures. I almost forgot that I left the Auto-Awesome feature on. It did wonders to my photos. I love it!
Auto Awesome photos & moviesAuto Awesome creates fun new versions of your photos and videos. Your photos will be combined into short animations, wide panoramas, or merged into group shots where everyone looks good. You\’ll know when an Auto Awesome photo or movie has been created by the icon. —SOURCE
It can auto enhance, add effects and help you build up a home movie from your photo and video collection.
Auto awesome is on by default. If you don\’t want it, just configure it on the settings.
