An example of an HDR image. This is from one RAW file.
Actually it is from three RAW files as I copied the
original RAW two times, brought them into Photomatix,
set the EV to 0; -2; and +2. Photomatix combined the
files and I selected the tonal details.

The original is here http://www.pbase.com/image/86657056

I like the light and tonal differences of the HDR image.
