After reading this book, you will never look at the sky or the sea in the same way again. Accompanied by beautiful photographs, including some rare sights in the sky, the book systematically covers atmospheric phenomena related to light and colour. For photographers it's a great book that will help you understand light effects in nature. The book is resplendent in the spirit of science: the topics are classified by the type of explanation for them: shadows, reflection, refraction and so on. This makes perfect, natural sense and really holds the book together. Some of the explanations include modest equations, tables and so on, but the text is always lively and readable. If you're scared of mathematics, buy it for the pictures. But be warned: this book will inspire you to go to Antarctica, chase solar eclipses, buy a telescope, and demand a window seat on every plane you fly for the rest of your life.
