Here how I did it:
Created levels layer, but didn't change anything except for the blending mode: Screen.
Flattened image.
Created new adjustment layer: Channel mixer, and used it to convert to black and white using the red channel.
Changed blending mode of the bw layer to Overlay. It became colorful with high contrast.
Added a vignette.
Obviously, it was all done after I changed canvas size and pasted another copy on her left, then rotated it to create the mirror effect...
Oh... I forgot to say that I also used LAB sharpening...
