The quality of our water—especially drinking water—is becoming an increasingly important issue. Andreas Schulz uses a groundbreaking photographic process to make the quality of various kinds of water instantly visible to the non-specialist. Through "crystal pictures," he demonstrates that water from different locations and treated in different ways will display substantially different characteristics. The quality of mountain spring water, for example, is different from water taken from a metropolitan system or from an old well. Water is affected by the way it flows—say, whether it is channeled through straight or bent pipes. Using water samples from many parts of the world, this remarkable and beautiful book provides a unique insight into the world of water—its life cycles, its nature, and its structures.
