Photos is divided into three tabs: Photos, Shared and Albums
In iOS 7, Photo automatically organizes photos into: Collections, Moments and Years
Collections is a grouping of moments such as your trip to San Francisco. The photos are organized into Moments according to date and location.
Years is quite simple, photos and videos are grouped by year.
The new iOS 7 sharing menu includes a scrollable list of apps and other iPhones to make sharing photos more simpler.
Photos in each view is displayed as a collage of tiny thumbnails.
You can tap on the thumbnail in any of the views to see a slightly bigger version of the photo or video.
You can swipe through the entire collage this way. If you release the finger it will open the photo or video.
With iCloud, you can share your favorite moments with your favorite people by creating a shared photo stream.
They can post photos, videos, and comments to your stream, and it all appears on everyone’s iOS devices – automatically.
The new Activity view lets you see the latest updates from all your shared streams in one place.
