Google announced the launch of new Google+ Communities today. These can provide public or private membership, and come with the option to start hangouts and plan events with community members.

“From photography to astronomy (and everything in between), Google+ has always been a place to crowd around common interests and meet new people,” says Google SVP Vic Gundotra. “What’s been missing, however, are more permanent homes for all the stuff you love: the wonderful, the weird, and yes, even the things that are waaay out there.”

Examples of Communities that are rolling out:

You can share with communities from any +1 button. You can access communities themselves by clicking the new “communities” icon, which is also rolling out on desktop. It will hit mobile soon, Google says.

The company also announced Snapseed for Android. You may recall that Google acquired Snapseed and its makers Nik Software earlier this year. Now, we’re seeing it implemented.

“Great pictures aren’t taken, they’re made—and Nik Software has been helping people make awesome photos for years,” says Gundotra. “Having welcomed Nik to the Google family, we’re excited to bring their Snapseed app (last year’s iPad app of the year) to Android.”

With Snapseed, you can make basic adjustments to photos like tuning, straightening and cropping. You can use creative filters, and utilize Control Point technology to enhance photos. It also comes with the ability to share creations via Google+ and other services.

Snapseed is rolling out for Google Play and an update is rolling out to the App Store (both free).
