Surreal Image Manipulations By nois7

The photo manipulations of Robert Jahns — known to most as nois7 — ride a thin line between reality and the impossible. Mixing cities with frozen arctics, putting rollercoaster drops at the top of skyscrapers, and showing us what it'd be like to skateboard through the Parisian sky are just a few of his optical works of art. See a few of his surreal photography tweaks in the gallery above.
