Wow! How simple things have become over complicated. I did a search so I could explain better and almost everything is videos. Can't people read anymore?
My fault, I was working the last week, Sunrise to Sunset (as hired help) and I didn't answer the question except saying Pro lighting. What I meant was, this could be a two or three or four light setup, back light to create an invisible background (that's the halo around the head) and one fill light - a softbox. main light in front, to create the portrait.
This is just an example, not the specific image. The answer is, something shot similar to this, and then they superimposed the portrait, into a background image. But the halo around the subjects head, is how it is isolated enough to add any scene, behind the head, without much complication.
See the more direct light on the right side of his face (as we view it) and the subtle shadow on the left?
And again, if it's the color or toning, then that's a different question and I missed it.
