Selective colour is a photography technique that refines the focus while adding a bit of monochrome flair. Indeed, this trick can extend to timelapse making as well; I found this timelapse by Liban Yusuf as an especially interesting way to view the world. Maybe it’s the reflective nature of a monochrome scene but with the unique hues kept around.
