iCloud: Photo Stream
The iCloud feature that lets you view your recent photos on all of your devices, and share selected photos with people you choose. Photo Stream includes My Photo Stream and Shared Photo Streams.
My Photo Stream stores the last 30 days of photos taken with your iOS device or imported from a camera to your Mac or Windows computer, and automatically pushes them over any available Wi-Fi or Ethernet connection to each of the devices that you set up to work with iCloud.
For example, if you take a photo on your iPhone (or save one to your Camera Roll), iCloud automatically stores the photo and pushes it to Photo Stream on your iPad, iPod touch, and other Mac or Windows computers.
With Shared Photo Streams, you can share just the photos you want with just the people you choose. Select photos from the Photos app in iOS 6, iPhoto or Aperture on a Mac, or even a Windows computer. Then name your new shared photo stream and enter email addresses of the people you’d like to share with. You can also add photos to your existing shared photo streams.
If you turn on Photo Stream when you set up iCloud, you can view My Photo Stream and Shared Photo Streams in:
The Photos app or iPhoto app (optional) on your iOS devices (My Photo Stream shows your last 1000 photos)
iPhoto or Aperture on a Mac (shows all photos added to your Photo Stream). Requires iPhoto v9.2 or Aperture v3.2. Shared Photo Streams require iPhoto v9.4 or Aperture v3.4.
The Photo Stream item under Favorites in a folder window of File Explorer (Windows 8) or Windows Explorer (Windows 7 or Windows Vista) (shows all photos added to your Photo Stream)
Photo Stream on your Apple TV
