iOS Question:

For those of us that end up with thousands of pictures in our Camera Rolls, Moments and Collections offer a better way to organize those photos. Just as iPhoto on the Mac can automatically break pictures into events, Photos on iOS can use metadata like time and location to create different “Moments”—all the pictures you took on Thursday at dinner, for example, or all the photos you snapped while on that weekend trip to the country. Collections are larger groupings of Moments—often all the photos you took in a general area (around your house) during a time period of often several months. Beyond that you can zoom out even further to a Years view that breaks down all the pictures you took in various (you guessed it) years.
