I took this shot whilst harnessed in at the top of a 90ft. waterfall freezzing my butt off. The specs are something like.....1/8th.sec. @ f5.6 shot at 400ASA on a Nikon D100. If you are ever in my part of the world (about 1hr. West of Sydney) between Nov. and March look me up and I will be happy to take you through one of the Blue Mountains Canyons.
