Now, Facebook can turn any photo into a 3D image

When the feature, used to create and share 3D photos, debuted in October 2018, it was largely dependent on the portrait mode shots taken by two or more cameras of a device.

Basically, the portrait photos were used by Facebook's AI to stitch different layers together and make a typical 2D shot three-dimensional, complete with the "depth" and movement of a 3D photo.

Now, to upgrade the tool for single-camera photos, Facebook has deployed a machine learning-based technique.

The system uses machine learning to infer the three-dimensional structure of an image and add depth and 3D effect according to it.

This ultimately transforms the image into a 3D post, without even using a portrait mode shot from a second camera.

Facebook says that the upgraded 3D Photos tool should work with images taken via iPhone 7 or higher or "a recent midrange or better Android device."

It might take a while to roll out on all phones, but once that happens, it will be relatively easier to share 3D posts.

Plus, you would also be able to share depth-rich 3D selfies on your Facebook.

In order to use the feature, you will have to update the Facebook app and follow the regular process to post content on the News Feed.

Just navigate to "What's on your mind", select "3D Photos", and pick any image of your choice - portrait or not - to post it with a 3D effect, maybe even with a caption.
