Query: Great book for expanding your basic knowledge of exposure.

I was really impressed with this book and how it took an average photographer through the steps towards understanding exposure. There are many fundamental concepts explained in a "layman's fashion" and I would highly recommend this book. There is only one chapter that enters into deep theory which the author suggests you may want to skip or come back to later. If you want to increase your basic understanding of film exposure, natural light and how film development plays an important part, then this book is for you!
