Infinity-edge pools are meant to be photographed. They are the ultimate in luxury, taking the concept of a private residential swimming pool to an entirely different level. Done right -- and they almost always are -- infinity pools give the illusion of a sheet of water dropping off over the edge of the property, like a waterfall, although you can't see or hear falling water.
That's because the water doesn't fall. The water that spills over the edge, usually into a catch pool or basin a few feet-or-so below the vanishing edge, is recycled back into the swimming pool. To work properly, an infinity-edge pool requires carefully calculated and maintained water levels, strong, solid construction to support thousands of gallons of water and a level edge over which the water can flow.
