In the last beta build of iOS 11, it was possible to cancel the effect of depth obtained by using the portrait mode of shooting. In other words, the owners of iPhone 7 Plus will be able to reconfigure the focus on the finished photo in such a way as to remove the blur and get the original frame not spoiled by post-processing algorithms.
To remove the background defocus effect, start the camera or the Photos application on a smartphone with iOS 11 beta 5 installed, find the photo you need and go to the editing menu by pressing the "Edit" button. Now turn off the depth mode by pressing the button at the top of the screen and confirm the changes.
The ability to remove the blur effect after the snapshot is created can be useful in cases where the proprietary algorithms responsible for creating a juicy bokeh do not work as expected. Previously, you were getting an already processed photo, which probably could have been more successful if it had not been forcibly changed by software methods.
