I picked the blue channel and then I used the channel mixer and I made the picture a little lighter by bumping up the red and then brining down the green.
I used gradient map, I created my own gradient map. I bumped up the lightness a lot more then the darkness. I then saved my gradient map and applied it to my picture.
I used the gradient map again and I created my own one. I bumped up the darkness and the lightness to create good balance. I then applied it to the photo.
