An HDR photo taken at night is where HDR photography really shines. This photo was taken during full darkness, but you can clearly see the lights of the buildings and the green grass of the park in the foreground.
How I took this HDR photo: This photo consists of three individual photos taken on the tripod. Each photo was about ten seconds in duration, and I used a shutter remote control to minimize any shaking of the camera while I took the pictures. After I had taken three photos at two EV increments, I processed them into one HDR image in Photomatix software.
