Adobe’s October 2023 update adds a new Lightroom Lens Blur panel. It’s flagged as Early Access, so it’s still in development, but you can use it right now and it’s actually rather impressive!
Blur in photography and photo editing
'Blur' is a word that can mean all sorts of different things. You can have blur caused by camera or subject movement, or you can have blur in out of focus areas of the photo. Blur is often used creatively in photo editing to subdue distracting elements in the scene, for example, so that the viewer's attention is focused on the main subject.
