When Photo Stream first came to iOS, it wasn’t too useful for anything other than moving your photos between devices. Photo Stream was an all or nothing deal – if you turned it on, all your most recent photos were synced between devices. At the outset, you couldn’t selectively sync photos, and you couldn’t share photos with anyone on a different iCloud account. That’s now changed.
If you haven’t heard, Photo Stream got a big upgrade in iOS 6. You can now create multiple streams, and, if you want, share individual streams with other iOS users. Cult of Mac has a pretty detailed post explaining how the whole thing works.
I can see this coming in handy at some point. My current problem? Nobody in my family has upgraded to iOS 6, so I have no use of shared photo streams. Ive wanted the feature since Photo Stream debuted, so I’m sure I’ll use shared streams at some point. Have you used them yet? Do you plan to?
