Perfect book, in the world of ever expanding number of tutorials on YouTube by famous photographers for understanding the technical aspects about photography. This book teaches you through carefully chosen photos from different genres, countries, cultures, eras, while cleverly adopting the principle of "Learn by Example", which has always worked for me in learning anything new. If you are like me, you will photograph differently(albeit better) after going through this book.
This books ends up helping you develop and introspect for a photographer's elusive X-factor that is so important for a success of a photograph, meticulously created with all the technical details done right.
