How was this photo taken in terms of aperture, shutter speed and ISO, and also how was it edited in post. Does anyone have a clue?

I can't see any motion blur in the people dancing behind, nor any light trails, so I'm guessing the shutter speed must have been at least 1/15 or similar. And there is some background blur, so maybe aperture 2.8-3.5 or so? How does one get that vibrant color and the almost movie-poster-like texture of the skin. It seems smooth but with detail and contrast.

Any thoughts on how to edit images taken at night clubs in this manner?
