The imager was a Nikon D300 camera set to ISO 200, autobracket and continuous shooting mode. The camera took a 9-frame bracket with 1-stop intervals in a span of 2.3 seconds. Exposures ranged from 1/500 to ½ second.
The individual frames were combined using a high-dynamic-range technique to reveal details beyond the dynamic range of any of the individual frames.
