One of my first HDR pics, only just got myself Photomatix and tried it out. Liked the grunge version of this pic. Taken in Geilo Norway. All of the houses in this neighbourhood have green/living rooftops and just looked like being part of the natural environment.

Canon EOS 5D, Canon EF 24-105mm, lens @ 47mm, t=1/60, f/22, ISO 200, handheld, HDR from single raw tonemapped in Photomatix.
