Most landscapes in this gallery were shot with a modified camera with Hitech IR filter (they say it's 720nm, but I'd rate it at some 670-690nm).
For the latest work, mostly weddings, I use a special combined filter that lets most IR and some visible light in, for out-of-camera blue sky and natural skintones.
I hope to update my website with english version and some more IR-mod information in a month or two, so you might want to stay tuned with my FaceBook account:
