This is a HDR of the Twin Falls waterfalls at Springbrook National Park in the Gold Coast Hinterland. It was a very cloudy and very wet weekend, so I had to use HDR to prevent the sky from blowing out badly.
These falls are quite high and an impressive sight. If the weather were better I would have been keen for a swim in the pool. Maybe next time 
This was blended from 5 photos. To get the 5 shots, I set the camera exposure bias to -2.0 EV, then took 3 bracketed shots at /- 2.0 EV (giving -4, -2 and 0 EV) then quickly set the exposure bias to 2.0 EV and took 3 more bracketed shots (giving +4, +2 and 0 EV). I then have shots ranging from -4 to +4 EV in 2 EV steps. I delete 1 of the duplicate 0 EV shots and blend the remaining 5 in Photomatix.
This is a neat little trick if the normal +/- 2.0 EV bracketing is not enough for the scene being shot. In this case the white cloud above the waterfall was blown out in every shot except -4 EV.
