There are a bunch of reasons to remove the background from a photo. You might just hate the background — a perfect portrait ruined by crowds, or ugly construction work, or both. You may want to remove the background in order to extract the subject — maybe you’re doing some kind of Photoshop trick, or making a greetings card.
Whatever your reasons, it’s easy to do. Removing the background from an image used to be a nightmare. Now, you just need the right app. And if you’re a regular with our Cult of Mac photo how-tos, you probably have that app already.
The Portrait Mode in the iPhone XR and XS is hands-down amazing. In the time it take to snap a photo, the camera scans the depth of the image in front of it, and uses that data to blur the background, and make the subject pop out, sharp. But it doesn’t always work. The depth detection gets confused by glass, for example, ruining what could have been an amazing image.
Today we’re going to use and app called Focos to fix these depth glitches. Focos is an all-round focusing powerhouse of an app, recently updated to support the iPad, including the new iPads Pro. The area we’ll focus on today (sorry) is the ability to edit the depth map, and paint back in the glass or hair that the iPhone missed.
