0. Prepare your base by sharpening, blurring, blah blah blah.
1. This tutorial works best on lighter pictures. If yours is a bit dark, then you may need to duplicate and set to SCREEN. Mine was okay as it was, so I duplicated and set to SOFTLIGHT 100%.
2. Create a new layer and fill with # 000b39. Set to SOFTLIGHT 100%.
3. Duplicate this layer  and set it to EXCLUSION 100%.
4. Take this texture by colorfilter and set to SOFTLIGHT 100%
And that's it!
