What do you mean, being sentenced to death in full focus?

This is not a photographic term, but expresses the author's mood, just like the person or thing he has been paying attention to, which is blurred by the sudden flash and makes the person or thing he was originally concerned about disappear here.

For example, when you are looking at people or things in front of you, suddenly someone flashes in front of you, and your eyes will be blurred, and you will lose the people and things you are looking at.

This can also be used to describe the drift of feelings.
