Apple iPhone 13 brings portrait mode for video

The new cinematic mode "anticipates when someone is about to enter the frame" and shifts focus to them, Apple said - something known as "pull focus".

It is the only smartphone that lets users edit this effect after shooting, Apple boss Tim Cook said.

However, most other features on the new model were incremental updates over previous versions.

The event was also overshadowed by news of a new security flaw in Apple devices which could expose users' messages.
