Facebook launched a 3-D photo feature, giving viewers a chance to see photos with 3-D-like depth. A user can pan, tilt and scroll through a photo, giving it a bit of motion or activity. The photos become truly 3-D when viewed through virtual reality tech. Facebook users who want to post a 3-D photo snap a picture in “portrait” mode with a phone that has dual-lens compatibility. The pic can then be shared on Facebook as a 3-D photo; the social network automatically adds layers to it to bring out the 3-D effects and engage viewers in the news feed.
