One feature that I love about this book is that each page covers a single concept, a single tool, or trick that will make your iPhone photos to the next level. This feature makes it very easy to scan through the book and find the particular subjects that you are interested in.
I think it is particularly significant that Scott decided to write this book since Scott is a long time professional photographer and photographic teacher it shows the importance and increasing popularity of iPhone photography.
Even though iPhone photography has been around for years I've never found a comprehensive book like this about the subject. Thanks Scott - great work!
