Function"Depth"
New smartphones also support the function "Depth". This is how Apple describes it:
Improved portrait segmentationallows you to make better portraits with professional bokeh blur. The new function "Depth" allows you to adjust the level of background blur in real time, and already on the finished images. Portrait mode with the “Depth” function is also available for the TrueDepth front camera.
Requirements
To use the new features, you need:
- iPhone XS, iPhone XS Max, iPhone XR and newer.
- Standard Camera application.
- Mode "Portrait" in the camera.
You can adjust the real-time background blur only in iOS 12.1.
Preview at real of time
The version of iOS 12.1 will be able to adjust the depth of the image in real time right in the camera.
You can select the level of background blur and then take a picture. For now, the Camera application has an “f” icon in the upper right corner for adjusting the aperture level.
Even if you select the degree of blur before you take a picture, you can adjust it and then on the finished picture. In addition, you can remove the blur effect altogether.
how works cameraiPhone
With the release of iOS 11 in September 2017, Apple began to read and save data on the depth of the images along with the portrait shots, making it possible to blur the background.
The camera sensors of the new iPhone have been improved, thanks to which the bokeh effect was brought to a new level with the release of iOS 12 and the new iPhone XS.

New iPhone models can capture muchmore details about the depth of images thanks to faster camera sensors and a new A12 Bionic processor, as well as machine learning and a neural engine. That is why Apple managed such a beautiful bokeh effect in the pictures.
As a result, portrait shots look much better than before.
Segmentation of images allows you to interact with portraits in a new way, because the object is better separated from the background.
New portrait segmentation APIs will also allow developers to use it in their applications. Some third-party cameras, like Halide, already have support for new features.
Due to segmentation, the Depth function is also possible. With it, you can make the bokeh effect more or less aggressive.
Portraits made on the new iPhone, will be more detailed thanks to the algorithms of computational photography. The system will better recognize the edges of hairstyles, accessories, etc.
