Photos automatically creates Memories—but you're the best curator of your photos and the stories behind them. So you can make a Memory from any Moment, Collection, Year, or Album in your photo library.
On your Mac, open an Album and click Show as Memory in the header. If you're in the Photos tab, click the title of a group of photos to open them as a Memory.
On your iPhone, iPad, or iPod touch, tap on the header of any Moment, Collection, Year, or Album. Scroll to the bottom of the screen and tap Add to Memories.
Want to save a memory for later? Scroll to the bottom of the screen and tap or click Add to Favorite Memories. You'll find it in the Favorite Memories album of your Photos app. If you decide that you don't want to save a Memory anymore, tap or click Remove from Favorite Memories.
When you add a Memory to your Favorites, you preserve it and keep it from going away when Photos creates new Memories.
You can also share your unforgettable experiences with friends and family. On your iPhone, iPad, or iPod touch, you can share Memory movies just like you would share any other video. Play a Memory movie, then tap on it to show the editing and sharing options. Tap 
and choose to share the movie via Messages, Mail, iCloud Photo Sharing, Facebook, YouTube, and more.
On your Mac, you can share the photos and videos that are contained in a Memory. Click 
to share through Mail, Messages, iCloud Photo Sharing, Facebook, and more.
