How to create Facebook 3D Photo on iPhone
Facebook 3D photos are a unique way to have your post stand out.
Created one requires an iPhone that has a portrait mode option. That is iPhone 7 plus, 8 plus, X or higher.
When you take the portrait mode picture, make sure you are far enough for the background to get blurry. Then create a post on Facebook and choose 3D photos. It will pull up all the pictures you've taken in portrait mode.
