How to synthesize thirty years of photography in a photography book?I have tried to do it with a 222 pages volume entitled "Multitudes" (only available in Italian language at now), combining similar or complementary (for shapes, colors or geometry) pictures, adding some brief thoughts or suggestions, and divided it into seven chapters: "The spirituality of mankind", "Beyond the clouds", "The enchantment of the forest", "Echoes of the Beyond", "Altitudes", "The Prayer of the Earth", "Sunsets and sunrises".
