When mountains are reflected in water they stand on their heads. This illustrated book by Simon Walther presents color photographs of mountain panoramas, lake refelctions, and whimsical cloud formations. All are based on the pleasure of tuning things upside down until illusion and reality are confusingly intermingled. A book to leaf through and wonder, but also an example of the fascinating phenomenon of symmetry in the playful interaction of hard facts and the gentle flow of reflection.
