It’s common to assume it’s impossible to improve photography by reading photography books. Since your job as a photographer is to have the necessary equipment and just shoot using it, the theoretical explanation of how to do it seems unnecessary. All you need is a camera, a model, and many hours of practice.
Well, it’s true that gaining all the photography skills by reading some pages of a photography book is questionable. But that doesn’t mean all the texts are useless. A good photography book does a good job to improve photography knowledge. It inspires and offers some new photoshoot ideas.
But the best photography books are even better. They do a great job of these tasks!
