That photo is now public to anyone within around 100 feet of the place it was taken. So if anyone else in the restaurant fires up Color, they’ll see the photograph listed in a stream alongside other photos that have recently been taken in the vicinity.'
Correct me if I'm wrong, but when it comes to photo sharing, aren't the people in your immediate vicinity at the time you take a photo the people who are going to be the least interested in getting that photo shared to them?
