Book excerpt: "Olivo Barbieri is back with a new photographic project on the world's greatest waterfalls: from Victoria Falls (on the border between Zambia and Zimbabwe) to Iguazu (between Argentina and Brasil), from Khone Papeng (Laos/Cambodia) to Niagara Falls (Usa/Canada), The Waterfall Project presents a selection of massive water systems with their imposing, incessant energy flows, which - as usual - Barbieri portrays exclusively from an aerial perspective."--BOOK JACKET.
