‘…you can view and post 360 photos on Facebook. People will be able to discover these photos on your Page or right in News Feed, where they can pan around and explore the scene by simply moving the phone around or clicking and dragging on web — much as they can with 360 videos..

There are a few ways to create a 360 photo:

  • Take a panorama with an iOS device or Samsung Galaxy phone
  • Capture a 360-degree photo on your phone using an app like Street View or Google Camera
  • Take a 360-degree photo with a 360 camera, such as the Samsung Gear 360, RICOH THETA S, 360Fly, Giroptic 360 Cam, ALLie Camera or Panon.
