With Facebook, you can now post 3D photos to your timeline through the Facebook app, even if you have a phone with a single camera, the company announced today. In theory, this should allow a lot more phones to take 3D photos – and Facebook says you can take 3D selfies with your front-facing camera too.
The feature, which was first available in October 2018, was previously only available for phones with two or more cameras that could be used to take pictures in portrait mode. Previously, 3D photos used an image with every camera that Facebook could use to create the "depth" of a 3D image.
According to Facebook, this new single-camera technology uses machine learning to infer the three-dimensional structure of an image and achieve the 3D effect. Here is an animation the company has provided of how this depth generation process looks:
And here's an example from Facebook of how the technology could look in an image on your timeline:
According to Facebook, everyone with an iPhone 7 or higher or a "newer Android device of the middle class or better" should be able to use the 3D photo tool in the main Facebook app. However, it doesn't seem to be fully implemented yet. Currently I can only take 3D photos with pictures taken in portrait orientation on my iPhone 11 Pro.
