Yann Philippe's infrared landscapes in Norway

Photographer Yann Phillipe made this series of landscapes which are rendered using the infrared light spectrum, rather than visible light. The effect is dreamy and almost science-fiction-ey; forests become bright red while blues seem to get cooler.

I'm not sure if these images were shot on actual infrared film, or if he was using a filter to simulate the effect. As I understand, infrared film stock is really hard to find these days (which is a shame), so my guess is that these images are digital. Either way, they're gorgeous.
