Google+ Automatic Face Recognition in photos

Starting from today, a new feature on Google+ which works inside the photo app that will make it much easier for you to tag the friends in your photos that Google recognition engine believes match those you have already tagged.

This feature is completely opt-in and wont tag anyone unless you flip the on-switch, and as is natural this day and age, Google has made it abundantly clear that they do not mean to try to swallow your identity up with a barrage of I KNOW YOU alerts. You will upload your photos as normal, see that Google+ has some suggestions for you, and say yes or no to each of them.
