Book excerpt: "The Visual Toolbox is photographer David duChemin's curriculum for learning not just how to use a camera--but how to make stronger photographs. He has developed 60 lessons, each one a stepping stone to becoming more proficient with the tools of this art, and the means to create deeper visual experiences with your images. David introduces you to the technical side of the craft but quickly moves on to composition, the creative process, and the principles that have always been responsible for making great photographs; he shows you these principles and invites you to play with them, turn them on their heads, and try a different approach to create beautiful, compelling images with your camera."--Publisher's description.
