http://farm3.static.flickr.com/2042/2053594454_f4566779a6.jpg Thats the link to the image that I want to know how to shoot. I know that it requires a super fast shutter, but thats all I really know. Is it lit by flash? If so, why doesnt the flash light up the background? How is the background so black? how is only the disturbed water lit? Do they use a tank? if so, what shape? How big? Is it just water? Is it modified in anyway? Help?
