I am very intrigued by this photo. Can anyone shed some light into how this effect could be achieved?
I think that it's saturated a little bit, contrast increased and split tone was applied towards blue. Here's an example how you can split the tone using Lightroom 4.
In the first example, the Hue was 237 (blues) and Saturation value was 29
While in the second example, the Hue was also 237 and Saturation value was 100. As you can see this image is more blueish than the first one
