The iPhone’s incredible Portrait mode does a great job of blurring the backgrounds of photos, making the subject stand out from busy backdrops. (Apple also uses this depth information for its truly awful Portrait Lighting effects — has anyone ever gotten a good result from the Stage Light filter? — but that’s another story.)
What if you could use the depth information inside Portrait photos to get rid of the background entirely? Wouldn’t that be something? Well, yes it would. And if you have the right app, it’s really easy to remove photo backgrounds.
