Take fun snapshots and make short videos in Photo Booth. Right from there, you can share what you shoot on Facebook and Twitter. Use photos as your Messages icons. Assign them to friends and family in Contacts. And add photos to your iPhoto library. But the real fun starts when you use the effects and backdrops. Snap a photo of yourself at the Eiffel Tower or in outer space. Choose from nine effects that use facial tracking technology so effects look great whether you’re front and center - or left of center. Snap single photos or shoot multiples in a four-photo burst. You can even shoot and trim video clips, complete with effects. And see your Photo Booth photos full screen.
