What / How to do this style?

Hey guys,

Just wondering if anyone’s ever tried to do this style (I saw it on the Muchmusic.com site under “news” and in the “videos” section.

Sorry for the low-res resolution of this picture but I had to cap it from a video.

I took a picture of a night time skyline and inverted it to get the white parts.
But beyond that, I’m stuck. Does anyone know how to get the nice “dark” shadows and the semi-3d look?
