Uses:Selective Color
1)Duplicate your picture and set it to screen. This step depends on the darkness or brightness of your image. You need the image to be pretty light or the outcome will be completely different. The opacity on mine was 75%.
2)Create a selective color layer(Layers->New Adjustment Layer->Selective Color)
Reds:-100 / 0 / 100 / 0
Yellows:100 / 0 / -100 / 0
Neutrals:-22 / 0 / -13 / 14
3)Create another Selective Color layer
Reds:-35 / 0 / 9 / 0
Yellows:38 /0/ -14 / 0
Neutrals:19 / 0 / 0 / -11
