We’ve written a lot about the Focos photo app here on Cult of Mac, because it’s like the Photoshop of focus. The universal iOS app lets you edit the focus of your Portrait mode photos in crazy depth (pun intended). But v2.0 just launched, and it’s hands-down amazing.
Focos 2 uses machine learning to calculate the depth of any photo, and then apply portrait-style blur to it. That means you can take portrait photos on the iPad and, wildest of all, you can apply a portrait background blur to photos you’ve saved from the internet.
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.
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.
